x - 5

x - 3

(x - 5)(x - 3)

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

What about it? Factorise it?

2s2+7s-15 = (2s-3)(s+5) when factored

3x^2 -14x +15 = (3x-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)

502 + (20/(202) x 15) = 2500.75

2x57-99 equal 15

That can be factored to -((x + 5)(x - 3))

x = 1
