X + (x+10)= -21
x^2 + 10x + 21 = 0
(x+7)(x+3)=0
x= -7 x= -3
In a and b and C there are negative numbers AFTER positive numbers, so we know they can't be correct. in a list from least to the greatest all the negative numbers would come before the positive numbers.

Hello.
The answer is: (x−4)(x−6)
Factoring means we want something like
(x+_)(x+_)
We need two numbers that...
Add together to get -10
Multiply together to get 24
Try -4 and -6:
-4+-6 = -10
-4*-6 = 24
Fill in the blanks in
(x+_)(x+_)
with -4 and -6 to get...
(x-4)(x-6)
Have a nice day
