ZeHanzBest ResponseYou've already chosen the best response.0
Assuming Y=y, I see a 2nd degree polynomial in y. You're not asking a question, so I will just calculate some fun stuff associated with it... Factorize: (y1)(y4). Zeroes: (y1)(y4)=0, so y=1 or y=4. If f(y)=y^25y+4, then the graph of f is a parabola. There is a vertex when y is the mean of the zeroes: y=2.5. The value is f(2.5) = 2.25. The axis of symmetry of the parabola is x = 2.5. The derivative of f is f'(x)=2y5. Maybe there is something of value for you in this all. You also could consider asking a question ;)

Yes but you can't just solve a problem... You first need to know if you need to factor it. Find the zeros etc..

okkk, does this problem need to be factorized?

\[Y^25y+4\] because it is Y^2 we know it must factor down into (Y plus or minus something) (Y plus or minus something) because it is a negative followed by a positive we know that they are both (Y  something) (Y  something) (if you need explanation just ask) we are now looking for numbers that multiply to make 4 and add together to make 5 1x4 = 4 1+4 = 5 2x2 = 4 2+2 = 4 so it must be 1 and 4 (Y  1) (Y  4)
