Question

What is the coefficient of the third term of the trinomial? (In other words, what is C?)

(2x + 3) (4x − 1) = 8x²+ 10x − C

Answer 1

-3

Explanation:

You want to multiply (2x+3)(4x-1) which would give you:

-
`8x^2-2x+12x-3\\\\Simplify\\\\8x^2+10x-3\\\\`

And because the other equation must equal this one you can assume that C is -3
