Question

5x (x + 3) = 2x - 3 ​

Answer 1

Respuesta:

En decimales aproximados :

x = ( -13 ± (√109))/10

Explicación paso a paso:

5x (x + 3) = 2x - 3 ​

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

5x² + 15x = 2x - 3

5x² + 15x - 2x + 3 = 0

5x² + 13x + 3 = 0

x = ( -13 + (√109))/10 ∧ x = ( -13 - (√109))/10

en decimales :

x = -0.25596

x = -2.34403
