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

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

x = - 5

Solution steps

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

Expand

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

Expand

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

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

Move

2

to the right side

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

Subtract

x^{2} + 2 x

from both sides

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

Simplify

x = - 5

w, w \cdot (- 4 + z) = m z + 17

c = x + b

9 m = 4 m - 35

5 (x + 10) = - 50

- (x - 2) = x + 2
