Question

When the quadratic equation y = (x − 2)(3x + 1) is written in standard form, what is the value of the coefficient "b"?

Answer 1

-5

Answer 2

if you just multiply it together, you can figure it out

(x - 2)(3x + 1)
x(3x + 1) - 2(3x + 1)
3x^2 + x - 6x - 2
3x^2 -5x - 2 Standard form: ax^2 + bx + c
^ coefficient
