complete the square

3 + 2 x - x^{2}

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

Solution steps

3 + 2 x - x^{2}

Write in the standard form

a x^{2} + b x + c

- x^{2} + 2 x + 3

Write

- x^{2} + 2 x + 3

in the form:

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

Factor out

- 1

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

2 a = - 2 : a = - 1

Add and subtract

(- 1)^{2}

- (x^{2} - 2 x - 3 + (- 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} - 3 - (- 1)^{2})

Simplify

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

x, 3 x^{2} + k x + 12 = 0

(5 x - 1)^{2} = 49

x^{2} + 20 x - 5000 = 0

(m + 8) (m - 9) = - 16

8 x^{2} - 16 x + 3
