May you give me brainliest if it is right?
This is the product of the square of a binomial expression. Therefore, it will have two factors.
Square of a binomial: a² + 2ab + b² = (a+b)²
The process:
9x² + 24x + 16
= (3x)² +2(3x)(4) + (4)²
= (3x + 4)² or (3x+4)(3x+4)
I hope this helps :)
So, the negative would be divided out to make it 3, then square both sides to get rid of the square root and get 9, then subtract 15 and you get -6. <span />
