complete the square

y^{2} - 16 y

(y - 8)^{2} - 64

Solution steps

y^{2} - 16 y

Write

y^{2} - 16 y

in the form:

x^{2} + 2 a x + a^{2}

2 a = - 16 : a = - 8

Add and subtract

(- 8)^{2}

y^{2} - 16 y + (- 8)^{2} - (- 8)^{2}

x^{2} + 2 a x + a^{2} = (x + a)^{2}

y^{2} - 16 y + (- 8)^{2} = (y - 8)^{2}

(y - 8)^{2} - (- 8)^{2}

Simplify

(y - 8)^{2} - 64

r^{2} = 2

y^{2} - 24 y

2 x + (x - 4) (x + 1) = 9

8 x^{2} - 4 x = - 3

5 x^{2} - 5 x = 3 x - 3 x^{2}
