x2-2x-10-5 = 0

x2-2x-15 = 0

(x+3)(x-5) = 0

x = -3 or x = 5

Q: How do you factor x squared minus 2x minus 10 minus 5 equals 0?

If x squared -10 = 0 then x = the square root of 10

n2 - 100 = (n + 10)(n - 10)

20x2 - 3x + 10 does not have any real factors.

(5x - 2)(x - 5)

10 squared equals 100. 102 = 10*10 10*10 = 100

x2+2x-120 = (x+12)(x-10) when factored

The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
