complete the square

2 x^{2} + 20 x

2 (x + 5)^{2} - 50

Solution steps

2 x^{2} + 20 x

Write

2 x^{2} + 20 x

in the form:

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

Factor out

2

2 (x^{2} + 10 x)

2 a = 10 : a = 5

Add and subtract

5^{2}

2 (x^{2} + 10 x + 5^{2} - 5^{2})

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

x^{2} + 10 x + 5^{2} = (x + 5)^{2}

2 ((x + 5)^{2} - 5^{2})

Simplify

2 (x + 5)^{2} - 50

0.15 y (y - 0.2) = 2 - 0.5 (1 - y)

- 3 x^{2} - 8 x + 7 = 0

2 r^{2} - 11 r + 5 = 0

x^{2} - 10 + 9 = 0

a = a^{2} + 4
