Question

(x^2-x)(4x^2-4x-5)-6

Answer 1

(x"2-x)(4x"2-4x-5)-6. =x"2(4x"2)-x(4x"2)+4x(x)-5(x"2)+5x-6. =(4x"4)-(4x"3)-(4x"3)+(4x"2)-(5x"2)+5x-6. =4x"4 - 8x"3 - x"2 + 5x + 6

Answer 2

Step-by-step explanation:

(x^2-x) (4x^2-4x-5) - 6

4x^4 - 4x^3 - 5x^2 - 4x^3 + 4x +5x-6

4x^4 - 8x^3 - x^2 + 5x -6

4x^4 - 8x^3 - x^2 + 2x + 3x -6

4x^3 (x-2) - x(x-2) + 3(x-2)

(x-2) (4x^3 - x +3)
