Find each of the following products:
(5x + 7) × (3x + 4)
To find the product of the given expression we have to Horizontal method;
Horizontal method is the method where each term of one expression is multiplied with each term of other expression.
So, by using horizontal method,
We have;
= (5x + 7) × (3x + 4)
= 5x (3x + 4) + 7 (3x + 4)
= 15x2 + 20x + 21x + 28
= 15x2 41x + 28
