MEAP Preparation - Grade 7 Mathematics 2.78 Multiplication of a Monomial and a Binomial - III
Example: Find the product 5x^{3}(9x+7y). Solution:
5x^{3}(9x+7y) = 5x^{3}.9x + 5x^{3}.7y
= (5.9).(x^{3}.x) + (5.7).(x^{3}.y)
= 45(x^{3+1}) + 35x^{3}y
= 45x^{4}+35x^{3}y
Directions: Solve the following multiplication problems. Also write at least 10 examples of your own.
