Answer:
(2x4 + 11x2 - 5)
Step-by-step explanation:
((2•(x5))+(7•(x3)))-(5x-22x3)
((2 • (x5)) + 7x3) - (5x - 4x3)
(2x5 + 7x3) - (5x - 4x3)
2x5 + 11x3 - 5x = x • (2x4 + 11x2 - 5)
Factoring 2x4 + 11x2 - 5
Multiply the coefficient of the first term by the constant 2 • -5 = -10
Find two factors of -10 whose sum equals the coefficient of the middle term, which is
10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
-1 + 10 = 9
Hope this helps!
