complete the square

x^{2} + 2 x - 7

(x + 1)^{2} - 8

Solution steps

x^{2} + 2 x - 7

Write

x^{2} + 2 x - 7

in the form:

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

2 a = 2 : a = 1

Add and subtract

1^{2}

x^{2} + 2 x - 7 + 1^{2} - 1^{2}

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

x^{2} + 2 x + 1^{2} = (x + 1)^{2}

(x + 1)^{2} - 7 - 1^{2}

Simplify

(x + 1)^{2} - 8

(x - 1)^{2} = 40

v, e = \frac{1}{2} \cdot m \cdot v^{2} + m \cdot g \cdot h

21 x^{2} = 4 - 5 x

19 x^{2} = 8 x

x^{2} - 2 x = 3 x + 6
