Answer 1

Answer:

pq+q2r+6p+6qr

if p=2,q=3,r=4 then

2x3+3(3)x4+6x2+6x3x4

6+9x4+12+18x4

6+36+12+72

42+12+72

54+72

====126

Answer 2

Answer:

(p + qr) (q + 6)

Step-by-step explanation:

pq + q²r + 6p + 6qr = (pq + q²r) + (6p + 6qr)

                                = q (p + qr) + 6 (p + qr)

                                = (p + qr) (q + 6)
