Factories 15pq+15+9q+25p
Open in App
Solution
15pq + 15 + 9q + 25p
= 15pq + 9q + 15 + 25p
= 3q (5p + 3) + 5 (3 + 5p)
= 3q ( 5p + 3) + 5(5p + 3) [ use commutative property for addition]
= (5p + 3)(3q + 5)
= 15pq + 9q + 15 + 25p
= 3q (5p + 3) + 5 (3 + 5p)
= 3q ( 5p + 3) + 5(5p + 3) [ use commutative property for addition]
= (5p + 3)(3q + 5)
