Answer 2

Question

• Factorise p²+pq+pr+qr.

Solution

______________________________________

$\small\sf\red{⟼ {p}^{2} + pq + pr + qr } \\ \\\small\sf\red{⟼p(p + q) + r(p + q)} \\ \\\small\sf\underline\red{ ⟼ (p + q) (p + r)}$

______________________________________

Hence the factors are $\large\sf\underline\green{(p+q)(p+r)}$
