Question

Write the quadratic equation in standard form: 18 - 4x – 5x^2 = 3

Answer 1

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`
