complete the square

x^{2} + 8 x

(x + 4)^{2} - 16

Solution steps

x^{2} + 8 x

Write

x^{2} + 8 x

in the form:

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

2 a = 8 : a = 4

Add and subtract

4^{2}

x^{2} + 8 x + 4^{2} - 4^{2}

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

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

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

Simplify

(x + 4)^{2} - 16

m^{2} - 3 m + 2 = 0

x^{2} + 14 x - 5 = 0

x, x^{2} + y^{2} + z^{2} = 1

x^{2} - 10 x

x, y^{2} = x^{2}
