Question

What are the exact solutions of x^2 = 4 − 7x?

Answer 1

thanks :)

Answer 2

First, move the right numbers to the left (remember to change the signs in the process)

That way, you'll have a standard notation. An example of a standard notation is...
\[x^2+4x+5=0\]

Then, find you a, b and c values and plug them into the quadratic equation...

Answer 3

\[x={-b \pm \sqrt{b^2-4ac}\over2a}\]

Answer 4

Can you solve for x? :)
