Question

Express 3x-x^2 as m-(x-n)^2. Ill give brainliest to correct answer!

Answer 1

Answer:

$\frac{9}{4}$ - (x - $\frac{3}{2}$ )²

Step-by-step explanation:

Given

3x - x² ← factor out - 1 from each term

= - (x² - 3x)

Using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² - 3x

= - (x² + 2(- $\frac{3}{2}$)x + $\frac{9}{4}$ - $\frac{9}{4}$ )

= - (x - $\frac{3}{2}$ )² - 1(- $\frac{9}{4}$ )

= $\frac{9}{4}$ - (x - $\frac{3}{2}$ )²
