complete the square

x^{2} - 4 x

(x - 2)^{2} - 4

Solution steps

x^{2} - 4 x

Write

x^{2} - 4 x

in the form:

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

2 a = - 4 : a = - 2

Add and subtract

(- 2)^{2}

x^{2} - 4 x + (- 2)^{2} - (- 2)^{2}

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

x^{2} - 4 x + (- 2)^{2} = (x - 2)^{2}

(x - 2)^{2} - (- 2)^{2}

Simplify

(x - 2)^{2} - 4

r, v = π r^{2} h

5 x^{2} - 60 x = 0

x^{2} + 6 x

r, v = \frac{1}{3} π r^{2} h

2 x^{2} - 6 x = 6 x^{2} - 8 x
