Homework Statement
1, 2. Factorize completely:
80t^5-5t
3X-9X^2+12
solve: 3. 1/2x = 1/6+1/3X
4. A right-angle triangle has the hypotenuse 16.0, one of the short sides is 3 cm longer than the other. Area and perimeter?
Homework Equations
The Attempt at a Solution
1. 5t(16t^4-1)
2. x(3-9x)+12 are they completely factorized though?
3. I cross multiplied until I got: 18X = 5X^2 + 12X... can't get any further
4. no success
