MEAP Preparation - Grade 7 Mathematics 2.77 Multiplication of a Monomial and a Binomial - II
Example: Find the product of 5x^{2}(9x+7y). Solution:
5x^{3}(9x+7y) = 5x^{2}.9x + 5x^{2}.7y
= (5.9).(x^{2}.x) + (5.7).(x^{2}.y)
= 45(x^{2+1}) + 35x^{2}y
= 45x^{3}+35x^{2}y
Directions: Solve the following multiplication problems. Also write at least 10 examples of your own.
