Question

If A = 3x² + 5x - 6 and B --2x2 - 6x + 7, then A - B equals?

Answer 1

Answer:

x^2 + 11x - 13

Step-by-step explanation:

A = 3x^2 + 5x - 6

B = 2x^2 - 6x + 7

=> A - B = (3x^2 + 5x - 6) - (2x^2 - 6x + 7)

             = (3x^2 - 2x^2) + (5x + 6x) - (6 + 7)

             = x^2 + 11x - 13

I hope this helps!
