Remember these three formulas (really, learn these by heart):

{(a + b)}^{2}  =  a^{2} + 2ab +  b^{2}

{(a - b)}^{2} = a^{2} - 2ab + b^{2}

(a + b)(a - b) = a^{2} - b^{2}

The stated formula is a manifestation of the last of these three. So indeed,

(y + 15)(y - 15) = y^{2} - 225

What is the vertex of the graph y = x^2 + 6x - 5 ?
Dafna11 [192]
Given:  <span>y = x^2 + 6x - 5.  Then a = 1, b = 6 and c = -5.

The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.

Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:

y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14

Then the vertex is (-3, -14).</span>
