0 = x^{2} + 4 x + 1

x = 3 - 2, x = - 3 - 2

Decimal Notation

x = - 0.26794 \dots, x = - 3.73205 \dots

Solution steps

0 = x^{2} + 4 x + 1

Switch sides

x^{2} + 4 x + 1 = 0

Move

1

to the right side

x^{2} + 4 x = - 1

Rewrite in the form

(x + a)^{2} = b

(x + 2)^{2} = 3

For

the solutions are

f (x) = a, - a

Solve

x + 2 = 3 : x = 3 - 2

Solve

x + 2 = - 3 : x = - 3 - 2

The solutions to the quadratic equation are:

x = 3 - 2, x = - 3 - 2

x + x^{2} - 25 = 15 x + 47

(2 x - 3) (x + 2) = - 3 x

x^{2} - 4 = 23

x^{2} - 80 x + 1200 = 0

x^{2} - 9 x + 12 = 0
