Question

subtract 6p(p+q+r)-4q(p-q+r) from8r(-p+q+r)​

Answer 1

Answer:

Subtract 6(p+q+r) - 4q(p-q+r) from 8r(-p+q+r)

So, 8r(-p+q+r) - {6(p+q+r) - 4q(p-q+r)}

» - 8rp + 8rq + 8r² - {6p+6q+6r-4qp+4pq+4qr}

» - 8rp + 8rq + 8r² - 6p + 6q + 6r - 4qp + 4q² + 4qr

» - 8rp + 8rq + 4rq + 8r² + 4q² - 6p + 6q - 4pq + 4pq + 6r

» - 8rp + 12rq + 8r² + 4q² - 6p + 6q + 6r
