complete the square

s^{2} + 8 s + 20

(s + 4)^{2} + 4

Solution steps

s^{2} + 8 s + 20

Write

s^{2} + 8 s + 20

in the form:

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

2 a = 8 : a = 4

Add and subtract

4^{2}

s^{2} + 8 s + 20 + 4^{2} - 4^{2}

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

s^{2} + 8 s + 4^{2} = (s + 4)^{2}

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

Simplify

(s + 4)^{2} + 4

12 x^{2} - 4 x - 40 = 0

2 x^{2} + B x + 3 = 0

5 x^{2} + 7 + 3 x = - 3 x

15 a^{2} + 4 a - 3 = 0

5 m^{2} + 3 m = 2
