(x+1)^2-(x-1)^2=x+9

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

x = 3

Solution steps

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

Expand

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

4 x = x + 9

Move

x

to the left side

3 x = 9

Divide both sides by

3

x = 3

- 2 (\frac{3}{2})^{- 2}

96 = 84 - 12 r

\frac{20 n ^{3} + 15 n ^{2}}{20 n ^{2} + 10 n}

x^{2} = 81

x^{2} + 7 x + 1 = 0
