Best ResponseYou've already chosen the best response.0use the quadratic formula \[x=\frac{b \pm \sqrt {b^24ac}}{2a}, \] which A is the coefficient for the x^2 term B is the coefficient for the x term C is the coefficient for the x^0 term

Best ResponseYou've already chosen the best response.0Well it looks like I will need to start this from the beginning. This is new to me so I am lost. I have a word problem. It is about a ladder leaning against a bldg. distance from bottom of ladder to bldg is 18' less than the length of the ladder. How high up the side of the bldg is the top of the ladder if that distance is 1' less than the length of the ladder

Best ResponseYou've already chosen the best response.0Maybe I set it up wrong. I started with \[(x18)^2+(x1)^2=x^2\]

Best ResponseYou've already chosen the best response.0finding the roots give you the factor of the equation indirectly. because equation are in the quadratic form is (x  n) ( x n) with n being the root you have a factored equation. of \[( x  19+√(35)) ( x  19√(35))\]

Best ResponseYou've already chosen the best response.0ok. then I did this formula: \[x^236+324+x^22x+2=x^2\]

Best ResponseYou've already chosen the best response.0Then you get (x  25)(x  13) = 0 which is x = 25, 13

Best ResponseYou've already chosen the best response.0When you took (x  1)^2 Gem you had x^2  2x + 2 and it is actually x^2  2x + 1

Best ResponseYou've already chosen the best response.0ah ok that is why I got 326 instead of 325.
