Whoops i forgot to read the lesson :P 30 points

Step-by-step explanation:

I'll do 2.

Alright,Alex let say we have factored a quadratic into two binomial, for example

(5x + 3)(6x - 4)

If we set both of those equal to zero

(5x + 3)(6x + 4) = 0

We can used the zero product property in this case to find the roots of the quadratic equation.

This means that

if  \: ab = 0 \: then \: a = 0 \: and \: b = 0

This means we set each binomal equal to zero to find it root.

5x + 3 = 0

5x =  - 3

x =  -  \frac{3}{5}

6x + 4 = 0

6x =  - 4

x =  -  \frac{2}{3}

So our roots are negative 3/5 and negative 2/3 using zero product property

If f(x) varies directly with x and f(x) = 48 when x = 8 find the value of f(x) when x = 2
const2013 [10]
Here, f(x) = kx

k = f(x)/x
k = 48/8
k = 6

So, when x = 2, 
f(x) = 6 * 2
z = 12

In short, Your Answer would be: 12

Hope this helps!
