Question

Resolva as equações

a) (2x-1)=x-2

b) (2x²+15x-3)=x²+2x-3

c)(3x+2)=2x-3

d)(x-1)=3

Answer 1

a) (2x-1)=x-2           b) (2x²+15x-3)=x²+2x-3    c)(3x+2)=2x-3        d)(x-1)=3
2x-1=x-2                         2x²+15x-3=x²+2x-3       3x+2=2x-3           x-1=3
2x-x=1-2                     2x²-x²+15x-2x+3-3             3x-2x=-2-3          x=+1+3
x=-1                             x²+13x                               x=-5                   x=4
                             +3 -3 cortam

Answer 2

olha, a B eu acho que é impossivel pois dá 0
