Question

Find the product.
(5x + 2y)(x + y)

Answer 1

Answer: Simplified 5x^2+7xy+2y^2

Explanation:

5x*x=5x^2

2y*2=2y^2

2y*x=2xy

5x*y=5xy

Adding the finals together & simplifying you would get:

5x^2+7xy+2y^2

Answer 2

The product od the given question is
`5x^(2) + 2y^(2)` + 7xy

Explanation:

Formula

(a+b)(c+d) = a(c+d) +b(c+d)

=ac+ad+bc+bd

Here,

(5x+2y)(x+y)

= 5x(x+y)+2y(x+y)

=
`5x^(2)` + 5xy + 2xy +
`2y^(2)`

=
`5x^(2) + 2y^(2)` + 7xy
