x - 3
x - 5
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
(x - 5)(x - 3)
(X minus the cube root of fifteen) times (x squared plus the cube root of fifteen plus fifteen to the two thirds power)
3x^2 -14x +15 = (3x-5)(x-3)
2s2+7s-15 = (2s-3)(s+5) when factored
What about it? Factorise it?
502 + (20/(202) x 15) = 2500.75
That can be factored to -((x + 5)(x - 3))
2x57-99 equal 15
x = 1
