Question

3q(p-q)+2r(p-q)-S(q-p)
Can u solve it step by step

Answer 1

-3q² + 3qp + 2rp - 2rq + Sq - Sp

Explanation:

first part

3q(p-q) = 3qp - 3q²

second part

2r(p-q) = 2rp - 2rq

third part

S(q-p) = Sq - Sp

then we put it all together

3qp - 3q² + 2rp - 2rq + Sq - Sp

in the right place possibly

-3q² + 3qp + 2rp - 2rq + Sq - Sp
