x^2+1=(x+3)^2

Solution

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

Solution

x = - \frac{4}{3}

+1

Decimal Notation

x = - 1.33333 \dots

Solution steps

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

Expand

(x + 3)^{2} : x^{2} + 6 x + 9

x^{2} + 1 = x^{2} + 6 x + 9

Move

1

to the right side

x^{2} = x^{2} + 6 x + 8

Subtract

x^{2} + 6 x

from both sides

x^{2} - (x^{2} + 6 x) = x^{2} + 6 x + 8 - (x^{2} + 6 x)

Simplify

- 6 x = 8

Divide both sides by

- 6

x = - \frac{4}{3}

Popular Examples

5-i+(11-i)z=40+18i

5 - i + (11 - i) z = 40 + 18 i

-6(x+5)=3(x+11)

- 6 (x + 5) = 3 (x + 11)
