Question

Responder ecuaciones cuadraticas (te doy corona sí contestas bien)​

Answer 1

4x² + 6x = 0

2x(x+ 3) = 0

2x = 0       x + 3 = 0

x = 0/2     x = -3

x = 0

CS = (-3; 0)

5x² + 10x = 0

5x(x + 2) = 0

5x = 0       x + 2 = 0

x = 0/5       x =  -2

x = 0        

CS = (-2; 0)

x² + 4x = 7x

x² + 4x - 7x = 0

x² - 3x = 0

x(x-3) = 0

x = 0       x - 3 = 0

               x = 3

CS =(0, 3)
