1 point​

Answer 1

➪ (x + a)(x + b) = x(x + b) + a (x + b)

                   = x² + xb + ax + ab

                  = x² +  (b + a)x + ab

Answer 2

Answer:

(x +a)(x+b)

= (x)(x)+(x)(b)+(a)(x)+(a)(b)

=x²+bx+ax+ab

=x²+x(a+b)+ab

(x + a)(x + b) = x² + (Sum of constant terms)x + Product of constant terms.
