You basically have to use the quadratic formula to solve this since there are no factors of - 9 which add to give 6.
Then you use
To find which numbers will go into what place inside the quadratic equation.
So a = 1 (because x is alone)
b = 6
c = -9
Then you solve it. I've included a picture of how I did it and I got the answer x=-3+-3sqrt2
Answer: 30/40+16/40 and 15/20+8/20 pls mark brainliest
Step-by-step explanation:
You know that 3/4+2/5=23/20.
Now select the other expressions equal to that. They are: 30/40+16/40 and 15/20+8/20
