6x⁴ + 7x² - 10
6x⁴ - 5x² + 12x² - 10
x²(6x²) - x²(5) + 2(6x²) - 2(5)
x²(6x² - 5) + 2(6x² - 5)
(x² + 2)(6x² - 5)
The answer is 17/18.
You need to make the denominator the same on all the fractions.

2 11/78 you just have to simply multiply 64/143 x2 because since it can't be subtracted. And after you multiply 64/143, you just have to subtract normally which is 128-21 and 286-208. Then since your answer came out to an improper fraction, so you have to simplify by dividing 107 divided by 78. Then you will get your answer which is 2 11/78.
