Question

Ecuaciones Cuadráticas Incompletas de la forma ax^2+bx=0
x^2 + 5x = 0
2x^2 + 8x = 0
4x^2 - 3x = 0
2x^2 - 32x = 0
12x^2 - 24x = 0

Answer 1

Respuesta:

x² + 5x = 0  

x₁=0

x₂= -5

2x² + 8x = 0

x₁=0

x₂= -4

4x² - 3x = 0

x₁=0

x₂= 3/4

2x² - 32x = 0

x₁=0

x₂= 16

12x² - 24x = 0

x₁=0

x₂= 2

Explicación paso a paso:

Problema #1↓

$x^{2} + 5 x =0\\\\x ( x + 5)=0\\\\\\x=0\\\\x+5=0\\x= -5$

Problema #2↓

$2 x^{2} + 8 x =0\\x (2 x + 8 )=0\\\\x=0\\\\2 x +8=0\\2x = -8\\x= \frac{-8}{2}\\x= -4$

Problema #3↓

$4x^{2}-3 x =0\\x (4 x -3)=0\\\\x=0\\\\4x-3=0\\4x= 3\\x= \frac{3}{4}$

Problema #4 ↓

$2x^{2} -32 x =0\\x(2x-32)=0\\\\x=0\\\\2x-32=0\\2x= 32\\x= \frac{32}{2}\\x= 16$

Problema #5 ↓

$12x^{2} -24 x =0\\x(12 x - 24)=0\\\\x=0\\\\12x-24=0\\12 x = 24\\x= \frac{24}{12} \\x= 2$

Espero sea de ayuda!
