Answer:

x^2-x-12

Step-by-step explanation:

You can use the formula of FOIL, you go to each factor in the parenthesis and multiply by the other factors, the inside will first be x^2 then the middles will be 3x and -4x and the outside will be -12 then you simplify by combining like terms making the middle -x.

The formula for the surface area of a pyramid is: SA=1/2LP+B . which equation solves formula for p

jeka94

$S_A=\frac{1}{2}LP+B\\\\\frac{1}{2}LP+B=S_A\ \ \ \ \ \ |subrtact\ "B"\ from\ both\ sides\\\\\frac{1}{2}LP=S_A-B\ \ \ \ \ |multiply\ both\ sides\ by\ 2\\\\LP=2S_A-2B\ \ \ \ \ \ |divide\ both\ sides\ by\ "L"\\\\P=\frac{2S_A-2B}{L}$

Solve by factoring. Check your answer.

Virty [35]

To factor, you split the equation so the factors multiply to get the whole equation.
(x-2)(x+2)

Then, interpret the factors.
The zeros can be found at (2,0) and (-2,0).
x=2, x=-2
