Use the quadratic formula to solve the equation. –x2 + 7x = 8

The solutions are:

Step-by-step explanation:

Given the quadratic equation

-x² + 7x = 8

Solving using the quadratic formula

Subtract 8 from both sides

Simplify

For a quadratic function of the form ax² + bx + c = 0, the solutions are:

For a = -1, b = 7, c = -8

Separate the solutions

Similarly solving

Apply the fraction rule:  

i.e.

Therefore, the solutions are:

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
