x2+14x+40 = (x+4)(x+10) when factored
x^2 + 14x + 40 factorises as (x + 10)(x + 4) so the roots are x = -10, -4.
x2 + 14x + 48 = (x + 8)(x + 6)
x2 - 14x + 45 = (x - 9)(x - 5)
x=7
x2+14x+40 = (x+4)(x+10) when factored
x^2 + 14x + 40 factorises as (x + 10)(x + 4) so the roots are x = -10, -4.
(x + 10)(x + 4)
(x + 10) and (x + 4) are both factors
x2+14x+40 = (x+4)(x+10) when factored
x2 + 14x + 48 = (x + 8)(x + 6)
If you mean: x^2 +14x +24 then it is (x+2)(x+12) when factored
14x(x + 2)
(x2 + 14x + 49) = (x + 7)2
x2 - 14x + 45 = (x - 9)(x - 5)
x=7
