MEAP Preparation - Grade 7 Mathematics 2.80 Multiplication of a Monomial and a Binomial - V
Example: 5x^{3}(9x^{3}+7y^{3}) = _____ ? Solution:
5^{3}.9x^{3} + 5x^{3}.7y^{3}
= (5.9).(x^{3}.x^{3}) + (5.7).(x^{3}.y^{3})
= 45x^{3+3} + 35(x^{3}.y^{3})
= 45x^{6} + 35x^{3}y^{3}Directions: Solve the following multiplication problems. Also write at least 10 examples of your own.
