8 0

Answer:

(0,0) and (3,0)

Step-by-step explanation:

When you graph y= -2x^2+6x it turns out to be a parabola. So, that means that this parabola actually crosses two points on the x-axis; (0,0) and (3,0)

Hope this helps!

What is the factorization of 3x2 – 8x + 5?

tatuchka [14]

For this case we must factor the following expression:

$3x ^ 2-8x + 5$

We rewrite the middle term as a sum of two terms whose product is

$a * c = 3 * 5 = 15$

And whose sum is

$b = -8$

These numbers are:

-5 and -3

So:

$3x ^ 2-5x-3x + 5$

We factor the maximum common denominator of each group: $x (3x-5) - (3x-5)$

We take common factor $(3x-5):$

$(3x-5) (x-1)$

Answer:

$(3x-5) (x-1)$
