complete the square

x^{2} - 4 x - 3

(x - 2)^{2} - 7

Solution steps

x^{2} - 4 x - 3

Write

x^{2} - 4 x - 3

in the form:

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

2 a = - 4 : a = - 2

Add and subtract

(- 2)^{2}

x^{2} - 4 x - 3 + (- 2)^{2} - (- 2)^{2}

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

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

(x - 2)^{2} - 3 - (- 2)^{2}

Simplify

(x - 2)^{2} - 7

p^{2} = 169

1.5 x^{2} - 10 x - 16 = 0

x^{2} - 23 x - 50 = 0

5 x^{2} - 4 x + 7 = 0

x^{2} + 8 x + 16 = 36
