Well you could do 5 3/8 plus 3 1/4 and your denominator 4 can become a 8 so multiply 4x2 to get 8 and 2x1 to get 3 2/8 and add that to 5 3/8 to get the sum of 8 7/8

Answer:
(x+11)(x-2)
Step-by-step explanation:
To factorise: x^2+9x-22
You must first divide the centre term in such a way that the sum of the 2 values will be divisible by x squared and minus 22 respectively.
So x^2+9x-22 = x^2 -2x + 11x - 22.
Now factorize x^2 - 2x and 11x-22 individually.
x^2 - 2x = x(x-2)
11x - 22 = 11(x-2)
Since these both have the same value in the brackets, use 5at one of the brackets and the other is the combination of them together:
(x+11)(x-2)
