Question

What is the product of (x + 3)(2x – 1)

Answer 1

Umm
(X+3)(2x-1)
=2x square -x + 6x - 3
=2x square +5x -3

Answer 2

The product of
`(x + 3)(2x -1)=2x^2+5x-3`

Explanation:

Given : Two expressions (x + 3) and (2x – 1)

We have to find the product of given expression that is
`(x + 3)(2x -1)`

Consider the given expression
`(x + 3)(2x -1)`

Multiply each term of first bracket with each term of second bracket

`\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd`

we have,

`=x\cdot \:2x+x\left(-1\right)+3\cdot \:2x+3\left(-1\right)`

Simplify,
`-(-a)=+a`

we have
`=2xx-1\cdot \:x+3\cdot \:2x-3\cdot \:1`

Simplify, we get,

`=2x^2-x+6x-3`

Adding like terms, we have,

`=2x^2+5x-3`

Thus, the product of
`(x + 3)(2x -1)=2x^2+5x-3`
