Question

ncesito esta ecuacion con su prueba -8x+3x(2x+1)=5(x+1)-2x

Answer 1

-8x+3x(2x+1)=5(x+1)-2x
-8x+6x²+3x=5x+5-2x
6x²-8x+3x-5x-5+2x=0
6x² - 8x - 5 = 0
Bascara
a=6
b=-8
c=-5
(8+-√((-8)²- 4x6x(-5)))/ 2x6 = (8+-√(64+120))/12 =
(8+-√184)/12 = (8+-2√46)/12 = 
= x1= (8+2√46)/12 =2/3 + √46/6
   x2= (8-2√46)/12 =2/3 - √46/6
