# Solve the following quadratic equation by factorization method: 9x^2-25 = 0 - Algebra

Solve the following quadratic equation by factorization method: 9x2-25 = 0

#### Solution

9x2-25=0
(3x)2-(5)2=0
(3x-5)(3x+5)=0……... [a2 -b2 =(a-b)(a+b)]
(3x-5)=0 or (3x+5)=0
3x = 5 or 3x = -5
x =5/3 or x = -5/3

therefore{5/3,-5/3}  is the solution set of the given equation.
