Question

HELP! Monica is attempting o factor the expression 18x^2+27x-5. In her first step, she rewrites the expression as 18x^2+32x-5x-5.?

Which of the following statements is true about moincas work?


A.
The first step is correct. She should continue to factor the expression.
B.
The two middle coefficients add to the correct number, but do not multiply to the correct number.
C.
The two middle coefficients multiply to the correct number, but do not add to the correct number.
D.
The two middle coefficients do not add or multiply to the correct number.

Answer 1

The first term 18x^2 has the coefficient of 18. The last term is -5
Multiply the two values 18 and -5 to get 18*(-5) = -90

We need to find two numbers that
A) multiply to -90
B) add to 27

The numbers 32 and -5 add to 27, but they do NOT multiply to -90

So that's why the answer is choice B

Side note: the two values are actually -3 and 30 but this is just extra info at this point
