Answer 2

$\huge\underline{ \mathbb\red{❥A} \green{n} \mathbb\blue{S} \purple{w} \mathbb \orange{E} \pink{r}} \:$

◽(x+a)(x+b)

$\mathbb \blue{Heya \: Mate}$

◽as

◽x(x+b) + a(x+b)

◽(by simply splitting up the first bracket).

◽Multiplying out both brackets then gives

◽xx + xb + ax + ab,

◽which is equal to

◽x2 + ax + bx + ab, which is our final answer
