Question

which expression gives the solutions of -5+2x^2=-6x ?

Answer 1

((-b+/- sqrt(b^2 - 4*a*c))/2*a) this is the formula.
2x^2 + 6x - 5, in this, its basically ax^2 + bx - c
Substitute :)

Answer 2

bring over -6x
\[2x^2+6x-5=0\]

Now you can use quadratic equation to plug in the values and solve the equation.

\[\frac{ (-b \pm \sqrt{b^2-4ac}) }{ 2a }\]

Answer 3

Thank you both!

Answer 4

Youre welcome :)
