Question

3/4x+4=3(x-1)+5/2 qual o resultado?

Answer 1

3/4x+16x/4x=3x-3+5/2

3+16x=12x²-12x+10x

12x²-18x-3

Δ = -182 - 4 . 12 . -3

Δ = 324 - 4. 12 . -3

Δ = 468

x = (-b +- √Δ)/2a

x' = (- -18 + √468)/2.12 x'' = (- -18 - √468)/2.12

x' = 39,63330765278394 / 24 x'' = -3,6333076527839374 / 24

x' = 1,6513878188659976 x'' = -0,1513878188659974
