Question

Gente me ajudem 5x^2+3-17-x^2/2=8

Answer 1

5x^2 +  \dfrac{3}{4} - 17 -   \dfrac{x^2}{2} = 8 \\  \\  \\ 5x^2 +  \dfrac{3}{4}  -  \dfrac{x^2 + 34}{2} = 8 \\  \\  \\ 5x^2 -  \dfrac{2x^2 + 65}{4} = 8 \\  \\  \\     \dfrac{18x^2 - 65}{4} = 8 \\  \\  \\ \dfrac{18x^2 - 97}{4} = 0  \\  \\ =>  18x^2 - 97
