x^3 + x^ 2 - 25x - 25
= x^2(x + 1) - 25(x + 1)
= (x + 1)(x^2 -25)
= (x + 1)(x + 5)(x - 5)

(x - 7)(y - 9)
= x*y - 7*y - 9*x + (-7)*(-9)
= xy - 7y - 9x + 63

The vertex of the parabola whose equation is y = x^2 + 2x + 9 is (-1 , 8) .

x = -2/2 = -1
when x = - 1
y = (-1)^2 + 2*(-1) + 9
y = 1 - 2 + 9
y = 8

Harry will be 18 years old in 6 years .
Let Nick now is y , Harry now is x
y = 7x
y + 6 = 5(x + 6)
we ger x = 12
y = 84
x + 6 = 12 + 6 = 18
So Harry is 18 in 6 years
