complete the square

4 x^{2} + 8 x - 5

4 (x + 1)^{2} - 9

Solution steps

4 x^{2} + 8 x - 5

Write

4 x^{2} + 8 x - 5

in the form:

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

Factor out

4

4 (x^{2} + 2 x - \frac{5}{4})

2 a = 2 : a = 1

Add and subtract

1^{2}

4 (x^{2} + 2 x - \frac{5}{4} + 1^{2} - 1^{2})

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

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

4 ((x + 1)^{2} - \frac{5}{4} - 1^{2})

Simplify

4 (x + 1)^{2} - 9

x, ln (y) = - x^{2} + c

4 x^{2} + 8 x + 7

4 x^{2} - 8 x - 13 = 0

8 n^{2} + 8 n + 2 = 0

y, x^{3} - x y^{2} + 2 y^{2} = 0
