Question

X²(2 - 7x) (-x+2)
Expand the following exercise

Answer 1

Explanation:

Use FOIL method

(2 - 7x)(-x + 2) = 2*(-x) + 2*2 + (-7x)*(-x) + (-7x)*2

= -2x + 4 + 7x² - 14x {Combine like terms}

= 7x² - 14x - 2x + 4

= 7x² - 16x + 4

x²(2-7x)(-x + 2)= x² (7x² - 16x + 4)

= x²*7x² - 16x * x² + 4x²

`7x^(2+2) -16x^(1+2) + 4x^(2)\\\\= 7x^(4) - 16x^(3) + 4x^(2)`
