x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
Well you want to do 4x4=16 bring the one up, put the six below the (from the x4) and do (4x2)+1=98+1=9 9So next to the 4 on the left side write a 9 from the answer of (4x2)+1So your answer is 96!
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
The one which says: y2 = 4 - 4/25 x2
the answer is 8. because 2x2 equals 4 then 4x2 equals 8 so my finall answer is 8.
