Factor 2pq - 5qr + 10r - 4p.
Tresset [83]
The answer is B) <span>(q - 2)(2p - 5r) 

</span>2pq - 5qr + 10r - 4p = 2pq - 4p - 5qr + 10r
                                 = 2pq - 4p - (5qr - 10r)
                                 = 2p(q - 2) - 5r(q - 2)
                                 = (q - 2)(2p - 5r)
