Question

What are roots of (3x+7)(2x-5)=0

Answer 1

x = -
`(7)/(3)` , x =
`(5)/(2)`

Explanation:

Given

(3x + 7)(2x - 5) = 0

Equate each factor to zero and solve for x

3x + 7 = 0 ( subtract 7 from both sides )

3x = - 7 ( divide both sides by 3 )

x = -
`(7)/(3)`

and

2x - 5 = 0 ( add 5 to both sides )

2x = 5 ( divide both sides by 2 )

x =
`(5)/(2)`
