Question

Find the equivalent quadratic expression to (x+2)(x+1)

Answer 1

Answer:

x^2 +3x+2

Step-by-step explanation:

the question has been a bit expanded so this is what you should do next

x(x+1) +2(x+1) i used the figures in the first bracket to multiply the second bracket

then use the figures outside the bracket to multiply what is inside i.e

x×x =x^2 and so on that gave me

x^2 +x+2x+2 =x^2 +3x because there's like an invisible 1 +2
