Question

Formula general en 2x2-2=3x

Answer 1

Respuesta:

2x^2 - 2 = 3x

2x^2-2-3x = 3x-3x

2x^2-3x-2 = 0

X = -(-3)+- √((-3)^2-4(2)(-2))/2×2

X = ( 3+-√(9-8(-2)))/4

X = (3+-√(9+16))/4

X = ( 3+-√25)/4

X = ( 3+-5)/4

X1 = (3-5)/4 = -2/4 y -2/4 = -1/2

X1 = -1/2

X2 = (3+5)/4 = 8/4 y 8/4 = 2

X2 = 2
