Hello :
-8x² +98 =0
x² =98/8
x² = 49/4
x² = (7/2)²
(x= 7/2) or( x= -7/2)
-9 - 11 = 29 + 4
First, add -9 - 11 to get -20.
Second, add 29 + 4 to get 33.
Third, -20 = 33 is false, so there is not a solution.

First, find the least common denominator (LCD) of the two fractions.
Multiples of 16: 16
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16
The LCD is 16.
Second, make the denominators the same as the LCD. / Your problem should look like:

+
Third, simplify. The denominators are now the same. / Your problem should look like:

+
Fourth, join the denominators. / Your problem should look like:
Fifth, simplify. / Your problem should look like:
Sixth, convert to mixed fraction. / Your problem should look like:
