Question

Simplify the following expression: (5x^2 + 3x + 4) - (2x^2 - 6x + 3). If the final answer is written in the form Ax^2 + Bx + C, what is the value of B? Only enter the numeric value.

Answer 1

hint:

x - (y + z) = x - y - z

notice how the sign of each term inside the parenthesis changes when you distribute that negative through

Answer 2

so something like x - (y - z) turns into x - y + z
