MEAP Preparation - Grade 7 Mathematics 2.79 Multiplication of a Monomial and a Binomial - IV
Example: Find the product 5x^{3}(9x^{2}+7y^{2}). Solution:
5x^{3}(9x^{2}+7y^{2})
= 5x^{3}.9x^{2} + 5x^{3}.7y^{2}
= (5.9).(x^{3}.x^{2}) + (5.7).(x^{3}.y^{2})
= 45(x^{3+2}) + 35x^{3}y^{2}
= 45x^{5}+35x^{3}y^{2}Directions: Solve the following multiplication problems. Also write at least 10 examples of your own.
