Question

a/ 4x mũ 2 - 6x. b/9x mũ 4 y mũ 3 + 3x mũ 2 y mũ 4. c/. x mũ 3 - 2x mũ 2 + 5x

Answer 1

`#3107`

`a.`

`4x^2 - 6x = 2x(2x - 3)`

`b.`

`9x^4y^3 + 3x^2y^4 = 3x^2y^2(3x^2y + y^2)`

`c.`

`x^3 - 2x^2 + 5x`

`= x(x^2 - 2x + 5)`

Answer 2

a) 4x² - 6x

= 2x(2x - 3)

b) 9x⁴y³ + 3x²y⁴

= 3x²y³(3x² + 3y)

c) x³ - 2x² + 5x

= x(x² - 2x + 5)
