Put the equation y = x^2 + 26 x + 160 into the form y = ( x − h )^2 + k :

Step-by-step explanation:

To write the given quadratic equation in the form  y = ( x − h )^2 + k, we need to complete the square for the given equation.

y = x^2 + 26x + 160

Shift the constant to the left side of the equation:

y - 160 = x^2 + 26x

Divide the coefficient of x by 2 and add the square of the result to both sides of the equation:

26 / 2 = 13

So adding 13^2 to both sides of the equation to get:

y - 160 + (13)^2 = x^2 + 26x + (13)^2

y - 160 + 169 = (x + 13)^2

y + 9 =  (x + 13)^2

y =  (x + 13)^2 - 9
