Solving Quadratic Equations by Factoring - Another Example

[patrickjmt]

@Vospader21 i would use the quadratic formula to solve this. otherwise it is just tedious trial/error factoring if it does factor with 'nice' numbers

this beats school by a mile ty so much

Does taking the square root of both sides and then y+6=9 so y=3 is wrong ??

I'm sorry but I need you ASAP, I have a problem just like 2nd step the beginning problem was -2/5(3X+1)(4X-3)=0 and i did your steps and I got -2/5X=-1/3 and -2/5X=+3/4 do I do anything to that "A" value or do I just leave it

that method is a bit long. just multiply out the brackets and incorporate the -81 giving y^2+12x-45 = 0
two numbers that add together giving 12 and multiply together giving -45: 15 & -3
hence factorizes to (y-3)(y+15)

Um, I don't wanna waste your time, but I'm a little stuck halfway through the procedure. Here's my problem 23p=5p^2 + 24 Here's the first step I took.
0=5p^2+24-23p And that's as far as I've gotten. I don't know where to go from here.
