Y^25y+4

This Question is Open

Best ResponseYou've already chosen the best response.0Assuming 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 ;)

Best ResponseYou've already chosen the best response.0Yes but you can't just solve a problem... You first need to know if you need to factor it. Find the zeros etc..

Best ResponseYou've already chosen the best response.0okkk, does this problem need to be factorized?

Best ResponseYou've already chosen the best response.0\[Y^25y+4\] 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)
