Multiplying a Monomial by a Binomial Practice Worksheet
1. Multiply a monomial by a binomial
(i) 5ab × (3ab + 4)
(ii) (-2y2) × (x + y2)
Solution:
(i) Given, 5ab × (3ab + 4)
Step 1: Multiply the monomial with the first term of the binomial.
=5ab × (3ab) =15a2b2
Step 2: Multiply the monomial with the second term of the binomial.
=4(5ab)=20ab
Step 3: Write both the terms obtained in step 1 and step 2 together with their corresponding signs.
=15a2b2 + 20ab
Hence, By multiplying 5ab, (3ab + 4) we get 15a2b2+20ab.
(ii) Given, (-2y2) × (x + y2)
Step 1: Multiply the monomial with the first term of the binomial.

Step 2: Multiply the monomial with the second term of the binomial.
=(-2y2) × y2=-2y4
Step 3: Write both the terms obtained in step 1 and step 2 together with their corresponding signs.
=-2xy2-2y4
Hence, By multiplying (-2y2), (x + y2) we get -2xy2-2y4.
