Explicación paso a paso:
4x² + 12x - 8 - 7x +2 = 0
4x² + 5x - 6 = 0 método del aspa simple
4x - 3
x + 2
(4x - 3)(x + 2) = 0
4x - 3 = 0 => [tex]x_{1}[/tex] = 3/4
x + 2 = 0 => [tex]x_{2}[/tex] = - 2
- (x + 3)(x - 1) = 3x(x + 1) - 58
x² + 2x - 3 = 3x² + 3x - 58
x² - 3x² + 2x - 3x - 3 + 58 = 0
-2x² - x + 55 = 0
por -1 a toda la ecuación
2x² + x - 55 = 0
2x + 11
x - 5
(2x + 11)(x - 5) = 0
2x - 11 = 0 => [tex]x_{1}[/tex] = 11/2
x - 5 = 0 => [tex]x_{2}[/tex] = 5
- 3x² - 2(x + 3) = 5x(x - 3)
3x² - 2x - 6 = 5x² - 15x
3x² - 5x² - 2x + 15x - 6 = 0
- 2x² + 13x - 6 = 0
por -1 a toda la ecuación
2x² - 13x + 6 = 0
2x - 1
x - 6
2x - 1 = 0 => [tex]x_{1}[/tex] = 1/2
x - 6 = 0 => [tex]x_{2}[/tex] = 6
