Best ResponseYou've already chosen the best response.1if we can not give out direct answers that would be great! ... At least show it's really B for the equation \[y=x^2+2x24\] notice that the middle term is 2 and the last term is 24 so we need to find what two numbers we need to produce a positive 2

Best ResponseYou've already chosen the best response.1all possible combinations of 24 are 1 24 24 1 12 2 2 12 8 3 3 8 4 6 6 4 thank goodness for multiple choice, so we can use the 4 6 6 4 combinations

Best ResponseYou've already chosen the best response.1since or equation patter is a + and  we need to figure out which number has to be negative and which number has to be positive in order to achieve 2x and  24

Best ResponseYou've already chosen the best response.1I think that 4 and 6 will be perfect.. because of 2 reasons.. we know that (4)(6) = 24 and 4+6 = 2 so now by factoring we have \[y=(x4)(x+6)\] we can check using the FOIL method and it does come back to the original equation that we had earlier.

Best ResponseYou've already chosen the best response.1to find our 0's we can just let y be 0 and solve for x. I think you could handle it from here 0=(x4)(x+6) It's like trying to ask yourself what x value do I need for this to hold true.

Best ResponseYou've already chosen the best response.1@Caylahill do you want me to go further or can you handle 0=(x4)(x+6) and find all x's ?

Best ResponseYou've already chosen the best response.1you can just use inspection and see that there are 2 x values that will make the equation 0
