I have to turn this in in like 30 minutes and I am so confused.

anonymous · Answer

what are you confused about?

anonymous · Answer

i am not sure what the steps are to solve them and then on the third part i know the difference but i cant find any similarities

anonymous · Answer

The first equation is simply a difference of squares. Use the formula: $a^2-b^2=(a+b)(a-b).$ The second equation, get everything on one side first so that you have $x^2+2x-24=0$. Then find two binomials that expand to that quadratic. You're looking for two numbers that multiply to -24 and sum to 2.

what are the equations in standard form

anonymous · Answer

{x^2 = 16, x (x+2) = 24}
