1. x^2-8x-8?
2.6x^2+7x-3?
show work?
x^2-8x-8 doesn't factor in rational numbers. If you really need to, you can use the quadratic formula and the factor theorem to find:
(x - 4 + 2√6)(x - 4 - 2√6)
6x^2+7x-3 = (2x + 3)(3x - 1)
1. hey! okay so you put it into the X formula thingy. where you multiply the X squared with the -8 and the -8x is another number.
then you put -8 on the bottom of one of the X slots and -8 at the top since it is like the same answer.
then you try to find different numbers that can multiply to get -8 and if you add them together it also equals -8
so your answer should be not possible because no two numbers can multiply to be -8 and add to be -8.
2. okay so you use the X and multiply 6 times -3
then you plug it in so that you have -18 in the top slot and 7 in the bottom
then you try to find the two numbers
the numbers are 9 and -2
then you do (x+9) and (x-2)
x=9,-2
and if there is an equal sign
6x^2+7x-3=0
then it is x= -9,2 because you switch the negatives to positives and positives to negatives
but if there isnt an equal sign
6x^2+7x-3
then it is x= 9, -2
hope i helped!
