Answer:
As an improper fraction: 8463/32
As a mixed number 264 15/32
Step-by-step explanation:
1. Multiply the base number times the denominator, then add the numerator to that number, and put it over the original denominator.
2. Do this for all of the numbers
3. multiply straight across, top*top*top, then bottom*bottom*bottom numbers. That number will be your improper fraction. Then divide that top number by the bottom denominator, take it out, leave the remainder as the numerator, and you have your mixed number.
Standard form: ax^2 + bx + c = y
Steps to simplify:
2x^2 - 1 = 3x + 4
~Subtract (3x + 4) to both sides
2x^2 - 1 - 3x + 4 = 3x + 4 - 3x + 4
~Simplify
2x^2 - 3x - 5 = 0
(a = 2, b = -3, c = -5)
Now that we know what these values are, we can use the quadratic formula to solve.

Answer: x = 5/2 or x = -1
Best of Luck!
The third fin is the answer.
