If B=x−1 and A=3x2−x+1 find an expression that equals 2B - 2A in standard form

Question

Algebra homework that I'm stuck on

Answer 1

B = x-1

2B = 2(x-1) = 2x - 2

A = 3x² - x + 1

2A = 2(3x² - x + 1) = 6x² - 2x + 2

2B - 2A = 2x - 2 - ( 6x² - 2x + 2) = 2x - 2 - 6x² + 2x - 2 = ____ Combine like terms, put into standard form
