Question

expand the following (x+1)(x+2),, (x-1)(x+2)​

Answer 1

Hey there

Ans to the first one is x^2+3x+2

And ans to second one is x^2+x-2

Answer 2

Answer:

1) x^2 + 3x + 2

2)x^2 + x - 2

Step-by-step explanation:

1st one,

(x+1)(x+2) = x(x+2) + 1(x+2)

= x^2 + 2x + x + 2

= x^2 + 3x + 2

2nd one,

(x-1)(x+2) = x(x+2) - 1(x+2)

= x^2 + 2x - x - 2

= x^2 + x - 2
