slope intercept of\[0=6^2p+5p+1\]are you sure you typed it right?

try changing all the p's into x's if you see it better that way.

oh no! i meant for the p to be squared!

it should be 6p^2+5p+1=0 and i need to change that into xintercept form

find the xintercepts you mean then, so solve the equation

I'm not allowed to use the quadratic formula. i can only factor it

6p^2+5p+1=0 ( _p + _ )( _p + _ )=0 we need to fill in the blanks such that the last terms multiply to 1 and the first terms multiply to 6

okayyy and how do i find those solutions mathmatically?

good observation that it could be negative, but since everything is postive here we will just assume it is positive for now (_p+1)(_p+1) what pairs of integers multiply to 6 ?

1 & 6 2&3 aanndd thats it

right, and since we know that (3p+1)(2p+1)=0 that implies that either 3p+1=0 or 2p+1=0, or both so solve those two equations and you get your two values of x for which y is zero, i.e. where the graph intercepts the xaxis.

so (3p+1)(2p+1)=0 is tha answer? and i can use this process for every problem?

you should always doublecheck that you get the correct cross term to be sure you have done it right (3p+1)(2p+1)=0 6p^2+3p+2p+1=0 6p^2+5p+1=0 ^^ cross term when factoring something that looks like ax^2+bx+c=0 sometimes you can find numbers that multiply to a and c, but do not produce the correct b, so you should FOIL out what you have to be sure also, you are not done with the statement (3p+1)(2p+1)=0 you still need to follow what I said above and solve for p: since we know that (3p+1)(2p+1)=0 that implies that either 3p+1=0, or 2p+1=0, or both equal zero so solve those two equations and you get your two values of x for which y is zero, i.e. where the graph intercepts the xaxis.

oh, typo... should say: so solve those two equations and you get your two values of p for which the function is zero, i.e. where the graph intercepts the paxis.
