complete the square

s^{2} + 4 s + 20

(s + 2)^{2} + 16

Solution steps

s^{2} + 4 s + 20

Write

s^{2} + 4 s + 20

in the form:

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

2 a = 4 : a = 2

Add and subtract

2^{2}

s^{2} + 4 s + 20 + 2^{2} - 2^{2}

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

s^{2} + 4 s + 2^{2} = (s + 2)^{2}

(s + 2)^{2} + 20 - 2^{2}

Simplify

(s + 2)^{2} + 16

3 x^{2} - x - 12 = 0

(x + 4) (x - 2) = 0

x^{2} + 16 x = 80

a^{2} - a - 12 = 0

3 x^{2} - x - 14 = 0
