Answer:

The quadratic equation:


18-4x-5x^2=3

in standard form is:


-5x^2-4x+15=0

Step-by-step explanation:

The standard form of a quadratic equation is:


ax^2+bx+c=0

Given the quadratic equation:


18-4x-5x^2=3

Subtract 3 from both sides


\begin{gathered} 18-3-4x-5x^2=0 \\ 15-4x-5x^2=0 \end{gathered}

Rearranging the powers of x from the highest to the lowest, we have:


-5x^2-4x+15=0
