To factor this you need values that add up to 2 and multiply to -15

So you get 5,-3 then you put it into your equation for you b value

X^2+5x-3x-15

Then you can factor by grouping

X(x+5)-3(x+5)

So your factors are

(X+5)(x-3)

How do you do the bottom 4? Thanks!
alexandr402 [8]
Alrightie! So we are trying to isolate independent variables! WOO HOO! 

So for a.) y = mx + b which is the point-slope formula... do this :)

y = mx + b
y - b = mx + b - b
y - b = mx 

\frac{y-b}{x} =  \frac{mx}{x}
m =  \frac{y-b}{x}

b.) follow the same way I did above, but instead of dividing x, divide by m.

c.)  I = prt which is the equation for interest. 
divide each side by pr.

d.) This one is like a and b. So lemme show ya.

A - p = prt
\frac{A-p}{pr} =  \frac{t}{pr}
t = \frac{A-p}{pr}
