Step-by-step explanation:
f=x^3 + 4x^2 - 7x - 10
f=x^3 + 4x^2 - 7x - 10
=> x^3 + 6x^2 - 2x^2 + 5x - 12x - 10
=> x^3 + 6x^2 + 5x - 2x^2 - 12x - 10
=> x(x^2 + 6x +5) - 2(x^2 + 6x + 5)
=> (x - 2) ( x^2 + 6x +5)
=> (x - 2)(x^2 + 5x +x +5)
=> (x - 2)(x(x +5) +1( x + 5))
=> (x - 2)(x +5) (x +1)
Therefore x^3 + 4x^2 - 7x - 10 = (x - 2)(x +5) (x +1)
hope it help you ｡◕‿◕｡
take care bye (◔‿◔)
