Question

use factoring to solve y= x^2+2x-24

Answer 1

6 & -4

Answer 2

since it starts with x^2, the first part of each binomial will start with x. Since the second +/- symbol is negative, the signs in each binomial will be opposite.
(x+ )(x- ) Now we have to fill in the blanks with 2 numbers that multiply to give us 24 but subtract to give us 2 (the middle term).

y=(x+6)(x-4)
if you are trying to find the zeros, set each binomial equal to 0 and solve for x.
0=x+6, x=-6
0=x-4, x=4
Hope this helps

Answer 3

It does but im confused on which number comes first b/c there is a (4,-6) and (6,-4) to choose from

Answer 4

You must pay attention to both the sign and magnitude. The middle term is Positive, positive 2x. You must put the one first that when combined results in a positive 2x.

in this case the 6 must be positive so that the results or positive. If you used a -6 then you would of had a -2x which is not what you wanted.

Answer 5

oooo ok
