Find the product:9x2(5x + 7)

1.	Find the product:9x2(5x + 7)
Answer» 9x²(5x + 7) Let p, q and r be three monomials. Then, by distributive law of multiplication over addition, we have: P × (q + r) = (p × q) + (p × r) Now, = (9x² × 5x) + (9x² × 7) = (45x³ + 63x²) … [∵ a^m × aⁿ = a^m+n]

Answer»

9x²(5x + 7)

Let p, q and r be three monomials.

Then, by distributive law of multiplication over addition, we have:

P × (q + r) = (p × q) + (p × r)

Now,

= (9x² × 5x) + (9x² × 7)

= (45x³ + 63x²) … [∵ a^m × aⁿ = a^m+n]
