Question

Solve the equation using the quadratic formula.
2x(x-1)=3
Step by step please, thanks!

Answer 1

First multiply 2x(x-1) out
ad then make it equal to 0
Finally use the quadratic formula and solve for it.

Answer 2

if you expand 2x(x-1) = 3 what would it give you?

Answer 3

2x^2-2x=3
2x^2-2x-3=0
Is that the right equation?

Answer 4

Yes...

Answer 5

yes \(\bf \textit{quadratic formula}\\
{\color{blue}{ 2}}x^2{\color{red}{ -2}}x{\color{green}{ -3}}=0
\qquad \qquad
x= \cfrac{ - {\color{red}{ b}} \pm \sqrt { {\color{red}{ b}}^2 -4{\color{blue}{ a}}{\color{green}{ c}}}}{2{\color{blue}{ a}}}\)
