15.
(x - 5)(x + 3)
x2 - 19x + 60 = x2 - 15x - 4x + 60 = x(x - 15) - 4(x - 15) = (x - 15)(x - 4)
33/4
x=3
x - 3
What is 50 minus 30 divided 6 divided 9 plus 15 equals
x + 3
x + 5
502 + (20/(202) x 15) = 2500.75
(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
Without any parenthesis is: 92 - 2 * 15 + 16 - 8 = 59
What about it? Factorise it?
2s2+7s-15 = (2s-3)(s+5) when factored
3x^2 -14x +15 = (3x-5)(x-3)
That can be factored to -((x + 5)(x - 3))
