Question

Solve the equation

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

Answer 1

Answer:

x = - 13

Step-by-step explanation:

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

x^2 + 3x - 5x - 15 = x^2 + 4x - 7x - 28

-2x - 15 = -3x -28

2x - 3x = 28 - 15

- x = 13

x = -13

Answer 2

Hi there here's your answer :

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

$x^{2}$+3x-5x-15 = $x^{2}$+4x-7x-28

$x^{2}$-2x-15 = $x^{2}$-3x-28

$x^{2} -x^{2}$-2x+3x-15+28=0

x + 13 = 0

∴ x = -13
