complete the square

x^{2} + 12 x + 20

(x + 6)^{2} - 16

Solution steps

x^{2} + 12 x + 20

Write

x^{2} + 12 x + 20

in the form:

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

2 a = 12 : a = 6

Add and subtract

6^{2}

x^{2} + 12 x + 20 + 6^{2} - 6^{2}

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

x^{2} + 12 x + 6^{2} = (x + 6)^{2}

(x + 6)^{2} + 20 - 6^{2}

Simplify

(x + 6)^{2} - 16

x^{2} + 12 x + 13

8 y + 3 y^{2} = 35

- 2 x^{2} + 8 x - 3 = - 2 x + 5

16 x^{2} + 20 x + 4 = 0

- 5 x^{2} + 10 x - 2 = 0
