Question

verify (x+a)(a+b)=x^2+(a+b)x+a*b

Answer 1

Answer:

$\sf\fbox\red{Answer:-}$

Expansion of (x + a) (x + b)

(x + a) and (x + b) are binomials with one term in common. Let us multiply them. a b

(x + a) (x + b) = x (x + b) + a(x + b) = x² + bx + ax + ab

= x² + (a + b)x + ab

Hence,(x + a)(x + b) = x ^ 2 + (a + b) * x + ab
