Question

-3x^2-8x+1=-10x using quadratic formula
can someone explain it step by step im so confused

Answer 1

Hello @sciencewiz123 :
First of all transpose -10 x from Right Hand Side to Left Hand Side :
\[\large{-3x^2 - 8 x + 1 + 10x = 0}\]
\[\large{-3x^2 - 8x + 10x + 1 =0}\]
\[\large{-3x^2 + 2x + 1 =0}\]
^ This is what we have as in the form of quad. equation now. Solve this by suing quadratic formula given below :
\[\large{\textbf{root of the equation } = \frac{-b \pm \sqrt{b^2-4ac}}{2a}}\]
Where b is here 2
a is here (-3) and
c = 1
