Question

Solve by using factorization
9x²+6x+1=0

Answer 1

Answer:

9x² + 3x + 3x + 1 =0

3x ( 3x +1) + 1 ( 3x +1 ) =0

(3x +1 ) + (3x +1 )

therefore

x = -1/3

or x= -1/3

Answer 2

Step-by-step explanation:

9x^2+6x+1=0

9x^2+3x+3x+1=0

3x(3x+1)+1(3x+1)=0

(3x+1)(3x+1)=0

(3x+1)=0 or (3x+1)=0

x=-1/3 or x=-1/3.

There for roots of quadratic equations are -1/3 and -1/3.
