Answer:

a = 4,

b = -22,

c = -7

Step-by-step explanation:

                                  3 (2x - 5) + 4 (x² - 7x + 2)

expand brackets:    = 6x - 15 + 4x² - 28x + 8

                                = 4x² - 22x - 7

compare with:            ax² + bx + c

∴ a = 4, b = -22, c = -7

Hope this helps!
