Solve the following quadratic equations by factorization method.

= 15(x² + x² + 2x + 1) = 34(x² + x)

= 15(2x² + 2x + 1) = 34(x² + x)

= 30x² + 30x + 15 = 34x² + 34x

= 34x² + 34x – 30x² –30x – 15 =0

= 4x² – 4x – 15 = 0

= 4x² – 10x + 6x – 15 = 0

= 2x(2x – 5) + 3(2x – 5) = 0

= (2x + 3) (2x – 5) = 0

2x + 3 =0 or 2x – 5 = 0

2x = –3 or 2x = 5

or x =
