Question

factorization of quadratic polynomial​

Answer 1

Answer:

x^2-11x-10x+110

x(x-11)-10(x-11)

(x-10)(x-11)

x=10,11

Answer 2

Answer:

10 or 11

${x}^{2} - 21x + 110 = 0 \\ {x}^{2} - (11 + 10)x + 110 = 0 \\ {x}^{2} - 11x - 10x + 110 = 0 \\ x(x - 11) - 10(x - 11) = 0 \\ (x - 11)(x - 10) = 0 \\ x = 10 or11$
