x*(x+4)=x^2+8

Solution

x \cdot (x + 4) = x^{2} + 8

Solution

x = 2

Solution steps

x (x + 4) = x^{2} + 8

Expand

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

x^{2} + 4 x = x^{2} + 8

Move

x^{2}

to the left side

4 x = 8

Divide both sides by

4

x = 2

Popular Examples

m^{2} - m - 88 = 0

3 ∣ 3 x ∣ + 4 = 16

(49x^2-81)/(x^2-64)<= 0

\frac{49 x ^{2} - 81}{x ^{2} - 64} \leq 0

- 7 (m - 81) = - 91

-1<-(-9x-1)-5/2 x

- 1 < - (- 9 x - 1) - \frac{5}{2} x
