Question

3250x=3250x+9750-75x²-225x RESOLVA A EQUAÇAO DE 2GRAU COM DELTA E bhaskara SE FOR POSSIVEL!!

Answer 1

Respostas: As soluções são -13 e 10

Explicação passo-a-passo:

$75x^2+225x-9750=0\quad(\div\,75)\to\\\\\\x^2+3x-130\to\text{Bhaskara}\to\\\\\\x=\dfrac{-3\pm\sqrt{3^2-4\times 1\times(-130)}}{2\times 1}\to\\\\\\x=\dfrac{-3\pm\sqrt{529}}{2}\to x=\dfrac{-3\pm23}{2}\to\\\\\\x_{1}=\dfrac{-3-23}{2}\to x_{1}=\dfrac{-26}{2}\to\boxed{x_{1}=-13}\\\\\\\text{ou}\\\\\\x_{2}=\dfrac{-3+23}{2}\to x_{2}=\dfrac{20}{2}\to\boxed{x_{2}=10}$

Portanto, as soluções são -13 e 10

É isso!! :)
