Factor completely: −4x2 + 16x − 24
mr_godi [17]
First, you need to see which number all of these numbers have in common, and that is number 4. So, let's start:

-4(x2 - 4x + 6)

The expression in the brackets cannot be factored further, which means that the answer above is the complete factor of the original expression. Hope it helps. :)

X²+4x+20=0
andrezito [222]

Step-by-step explanation:

The general form of the quadratic equation is :

ax^2+bx+c

The given equation is x²+4x+20=0

On comparing the given equation and the general equation, we find that

a = 1, b = 4 and c = 20

Hence, the correct option is a=1 b =4 c = 20.

If the equation is 2x²+6x+5=0, then

a = 2, b = 6 and c = 5

If the equation is -2x²+x+5

a = -2, b = 1 and c = 5
