Ihonestly just don't get this question. i'll give 30 !

sorry about your other question but here is the answer to this one

ok so her is what I think you do...

you have the equation y=3(x+1)^2+4 you use the distributive property to get rid of the prenticies so 3*x=3x and 3*1=3.  

Then you have y=3x^2+3^2+4 both of the numbers have a square root because the 2 beside the parinticies so both of those are squared

then u square what you can square so it would them be y=3x^2+9+4 because you can't square a variable and a number  it stays the same but because 3^2 can be squared is become 3*3 which equals 9

Then u combine the like terms you have making it y=3x^2+13 because of 9+4=14

then it says that y=x^2        so you put x^2=3x^2+13

after that you subtract -3x^2 from both sides making it -2x^2=13 because +x^2-3^2=-2x^2 and 3x^2-3x^2=0 so that goes away and you keep the +13

that is when you would divide by -2 on both sides making it -x^2=-13/2 which also equals -6.5(we will be using the decimal soon) because -2^2 divided by -2=-x^2 and 13 divided by -2 is -6.5

then u would find the square root of that by-{equation:\/(-x^2)=\/(-6.5)} -->\/(-x^2) which equals x because we don't know what x is it turns into jus x then as we move on =\/(-6.5)  which when you use a calculator it equals 2.54950976 but I would just round to the nearest hundreths making it 2.55 and that would be your answer
