Question

X²+x-(a+1)(a-2)solve the factor

Answer 1

Answer:

−^2+^2+++2

Step-by-step explanation:

Apply the distributive property.

x^2+x+(−a−1⋅1)(a−2)

Multiply −1 by 1.

x^2+x +(−a−1)(−2)

Expand (−a−1)(a−2) using the FOIL Method.

x^2+x−a⋅a−a⋅−2−1a−1⋅−2

Simplify and combine like terms.

Simplify each term.

x^2+x−a^2+2a−a+2

Subtract a from 2a.

x^2+x−a^2+a +2
