Question

solve the following quadratic equation in factorization x2 -2x-120=0​

Answer 1

Answer:

12 or -10

Step-by-step explanation:

${x}^{2} - 2x - 120 = 0$

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