Question

a (a+1) x²+x-a
(a-1)​

Answer 1

Step-by-step explanation:

Equation at the end of step 1

(((a•(a-1))•(x2))+x)-a•(a+1)

STEP 2

Equation at the end of step

((a•(a-1)•x2)+x)-a•(a+1)

STEP 3:

Equation at the end of step 3

(ax2 • (a - 1) + x) - a • (a + 1)

STEP 4:

Final result :

a2x2 - a2 - ax2 - a + x
