complete the square

x^{2} - 10 x + 20

(x - 5)^{2} - 5

Solution steps

x^{2} - 10 x + 20

Write

x^{2} - 10 x + 20

in the form:

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

2 a = - 10 : a = - 5

Add and subtract

(- 5)^{2}

x^{2} - 10 x + 20 + (- 5)^{2} - (- 5)^{2}

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

x^{2} - 10 x + (- 5)^{2} = (x - 5)^{2}

(x - 5)^{2} + 20 - (- 5)^{2}

Simplify

(x - 5)^{2} - 5

6 x^{2} + 60 x + 246 = 0

8 - y = \frac{( y - 2 ) ^{2}}{3}

(5 x + 9)^{2} + 9 = 49

\frac{1}{3} x^{2} = 12

x, x^{2} + 2 x y + 3 y^{2} = 4
