(x+3)(x-1)=x^2+5

Solution

(x + 3) (x - 1) = x^{2} + 5

Solution

x = 4

Solution steps

(x + 3) (x - 1) = x^{2} + 5

Expand

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

x^{2} + 2 x - 3 = x^{2} + 5

Move

3

to the right side

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

Move

x^{2}

to the left side

2 x = 8

Divide both sides by

2

x = 4
