Question

When the quadratic equation y = (x − 3)(4x + 2) is written in standard form, what is the value of the coefficient "b?"

Answer 1

Are you familiar with FOIL? Standard form looks like:

ax^2+bx+c

Answer 2

can you combine like terms?

Answer 3

Yep, you definitely should.

Answer 4

For example, if you have 2 apples in one hand and 3 apples in the other, then you have 5 apples in all. This is like combining 2x+3x=5x as like terms. Keeping them separate is confusing and not really useful.

Answer 5

@makdog combine x+4x and -3+2
