Solve the following quadratic equations by factorization method.
3(x² – 6) =x (x + 7)–3

3(x² – 6) =x (x + 7)–3

= 3x² – 18 = x² + 7x – 3

= 3x² – 18 – x² – 7x + 3 = 0

= 2x² – 7x – 15 = 0

= 2x² – 10x + 3x – 15 = 0

= 2x(x – 5) + 3(x – 5) = 0

= (2x + 3)(x – 5) = 0

2x + 3 = 0 or x – 5 = 0

2x = –3 or x = 5

or x = 5
