Question

x²-2x = 120 solve the quadratic
equation by factorization method​

Answer 1

Answer:

here is your answer.

Step-by-step explanation:

${x}^{2} - 2x = 120 \\ {x}^{2} - 2x - 120 = 0 \\ {x}^{2} - 12x + 10x - 120 = 0 \\ x(x - 12)10(x - 12) = 0 \\ (x - 12)(x + 10) = 0 \\ x - 12 = 0 \: or \: x + 10 = 0 \\ x = 12 \: or \: x = - 10$
