The way you tell whether a value is a solution or not is to try it in the equation.
A. -4*7 +2 = -26 ≠ 26 . . . . not a solution
B. -4*6 +2 = -22 ≠ 26 . . . . not a solution
C. -4*-7 +2 = 30 ≠ 26 . . . . not a solution
D. -4*-6 +2 = 26 = 26 . . . . this is your solution
_____
Of course, you can also solve the equation.
.. -4x +2 = 26
.. -4x = 24 . . . . . . subtract 2 (the term that doesn't contain x)
.. x = -6 . . . . . . . . .divide by -4 (the coefficient of x)

Answer:
54
Step-by-step explanation:
90-36=54
p(x) × q(x)
= (3x² - x + 1) × (2x² + 3x - 2)
= 6x⁴ + 9x³ - 6x² - 2x³ - 3x² + 2x + 2x² + 3x - 2
= 6x⁴ + 7x³ - 7x² + 5x - 2
