Answer 2

Respuesta:

x = -1

Explicación paso a paso:

Solve for x over the real numbers:

(x + 1) (2 x + 5) = (2 x + 3) (x - 4) + 5

Expand out terms of the left hand side:

2 x^2 + 7 x + 5 = (x - 4) (2 x + 3) + 5

Expand out terms of the right hand side:

2 x^2 + 7 x + 5 = 2 x^2 - 5 x - 7

Subtract 2 x^2 - 5 x - 7 from both sides:

12 x + 12 = 0

Factor constant terms from the left hand side:

12 (x + 1) = 0

Divide both sides by 12:

x + 1 = 0

Subtract 1 from both sides:

Answer:

x = -1
