Rewrite the quadratic function in intercept or factored form<br> y=-40x+2x^2-2x
poizon [28]

Answer:

y = 2x(x - 21)

Step-by-step explanation:

The given quadratic function y = -40x + 2x^2 - 2x

This can be rearranged as

y = 2x^2 - 2x - 40x

Here the Greatest Common Factor is 2x, we can take it out and write the remaining term in parenthesis.

y = 2x(x - 1 -20)

y = 2x(x - 21)

That's the answer.

Hope this will helpful.

Thank you.

What is the center of the circle for this equation:<br> (x + 3)² + (y - 2)² = 25
Ksju [112]

The formula for the equation of a circle is (x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and <em>r</em> is the radius.

So we need to find the values of (h, k) in order to find the center of the circle.

If we simply line up the equation of our given circle with our formula,

we can see that -h = 3 or h = -3 and -k = -2 so k = 2.

So now we have our answer.

center ⇒ (-3, 2)
