Answer:

C. \ \frac{-2}{3} , \ \frac{-4}{5}\\\\D. \ -2, \ -4

Step-by-step explanation:

C.

30x^2 + 44x +16 = 0\\\\2(15x^2 + 22 + 8) = 0\\\\2(15x^2 + 12x + 10x + 8) = 0\\\\2(3x(5x + 4)+2(5x + 4))=0\\\\2((3x + 2)(5x + 4)) = 0\\\\Zeroes : 3x + 2 = 0 => x = \frac{-2}{3}\\

             5x+ 4 = 0 => x = \frac{-4}{5}

D.

10x^2 + 60x +80 = 0\\\\10(x^2 + 6x + 8)= 0\\\\10(x^2 + 4x + 2x + 8)=0\\\\10(x(x+4)+2(x+4))=0\\\\10((x+2)(x+4))=0\\\\Zeroes : x + 2 = 0 =>x = -2

            x + 4 = 0 => x= -4

Method One

You could divide by 5 right away.

20/5 = - 3 + x

4 = - 3 + x Add 3 to both sides.

4 + 3 = x

x = 7

Method Two.

You could remove the brackets. This is slightly longer, but some questions can only be solved that way.

20 = 5(-3) + 5x

20 = -15 + 5x Add 15 to both sides

20 + 15 = 5x

35 = 5x Divide by 5

35/5 = x

7 = x

Can y’all solve this one
Soloha48 [4]

(f g)(x) means f(x) * g(x), so plug the value of each function in:

(x+2)(x-4)

And solve by distributing using FOIL:

Firsts: x * x = x²

Outers: x * -4 = -4x

Inners: 2 * x = 2x

Lasts: 2 * -4 = -8

Combine them all together:

x² - 4x + 2x - 8

Combine like terms (the -4x and 2x):

x² - 2x - 8

So the second to last one is correct.
