Question

Solve the quadratic equation 27y^2-314y+699​

Answer 1

Answer:

$3; \frac{233}{27}$.

Step-by-step explanation:

1) to calculate the discriminant of the given equation:

D=(314/2)²-699*27=5776.

2) to calculate the roots of the given equation:

$\left[\begin{array}{ccc}y=\frac{157-\sqrt{5776} }{27} \\ y=\frac{157+\sqrt{5776} }{27} \end{array}$

$\ \left[\begin{array}{ccc}y=3\\y=\frac{233}{27} \end{array}$
