3/4+1/3=9/12+4/12=13/12 of an hour
13/12= 1 1/12
Answer:
(3x^2+y^2+2xy)(3x^2+y^2-2xy)
Step-by-step explanation:
9x^4+2x^2y^2+y^4
(3x^2+y^2+2xy)(3x^2+y^2-2xy)
Both terms are perfect squares. So you will factor using the difference of squares formula. a^2-b^2=(a+b)(a-b)
Take what the square is for every term.
9x^4. What squared is 9? 3 and take half of the power or 2. That's how you get the 3x^2
2x^2y^2 is the same way. 2xy and 2xy
y^4 is y but dived he powers by 2 to get y^2.
Take one of each and but in () like I have above.
