Best ResponseYou've already chosen the best response.1dont wry, this is going to be very easy :) First, we find xintercepts using the quadratic formula.

Best ResponseYou've already chosen the best response.1you need to figure out a, b, c values. and plug them above to get the xintercepts

ali1029

Best ResponseYou've already chosen the best response.1so a=1 b=2 c=3? what i dont get is that it wants me to put that equation in intercept and vertex form but those have h & k :o

Best ResponseYou've already chosen the best response.1b = 2 we will get to vertex/intercept forms later. first, get the xintercepts :)

Best ResponseYou've already chosen the best response.1ohhh i see what i did wrong! thank you :) so know what do i do?

ganeshie8

Best ResponseYou've already chosen the best response.1that gives, \(x = 1+2 ~~~ or~~~~ x = 12\) \(x = 3, 1\)

ganeshie8

Best ResponseYou've already chosen the best response.1we're done wid using quadratic formula. we got the xintercepts : 3, 1

Best ResponseYou've already chosen the best response.1so the intercept form would be : y = (x3)(x+1)

Best ResponseYou've already chosen the best response.1wat about vertex form ? how to get \(h\), \(k\) ... any ideas ?

ali1029

Best ResponseYou've already chosen the best response.1wow that was easier than i thought! thank you :) & no, not too sure :(

ganeshie8

Best ResponseYou've already chosen the best response.1vertec form is also easy, \(h\) lies exactly at the middle of both the intercepts : \(h \) = \(\large \frac{3 + 1}{2}\)

ganeshie8

Best ResponseYou've already chosen the best response.1\(h \) = \(\large \frac{31}{2}\)

ganeshie8

Best ResponseYou've already chosen the best response.1\(h \) = \(\large \frac{2}{2}\)

ganeshie8

Best ResponseYou've already chosen the best response.1\(h \) = \(\large 1\)

Best ResponseYou've already chosen the best response.1so vertex form wud be : \(y = (x1)^2 + k\)

ganeshie8

Best ResponseYou've already chosen the best response.1you still need to find \(k\)

ali1029

Best ResponseYou've already chosen the best response.1okay, so how do we find k now? :)

ganeshie8

Best ResponseYou've already chosen the best response.1put x = h = 1, in given quadratic. it gives u the \(k\) value

Best ResponseYou've already chosen the best response.1i need to figure out how to put y5=2(x+1)^2 in standard and intercept form & y=(x+2)(x3) in standard and vertex form :o

ganeshie8

Best ResponseYou've already chosen the best response.1wats the standard form ?

ganeshie8

Best ResponseYou've already chosen the best response.1y = ax^2 + bx + c this is the standard form right ?

ganeshie8

Best ResponseYou've already chosen the best response.1oh yes... thats right !

Best ResponseYou've already chosen the best response.1y5=2(x+1)^2 add 5 both sides y = 2(x+1)^2 + 5

ganeshie8

Best ResponseYou've already chosen the best response.1next, use the formula \((a+b)^2 = a^2 +b^2 + 2ab\)

ganeshie8

Best ResponseYou've already chosen the best response.1y = 2(x+1)^2 + 5 = 2(x^2 + 1^2 + 2x ) + 5 = 2(x^2 + 1 + 2x) + 5

ganeshie8

Best ResponseYou've already chosen the best response.1y5=2(x+1)^2 to put this guy in intercept form, u need to find its xintercepts. so put y = 0 05=2(x+1)^2 5/2 = (x+1)^2 \(\pm \sqrt{5/2} = x+1\) \( 1 \pm \sqrt{5/2} = x\)

ganeshie8
