The answer is 5400.000. Hope this helps.
The quadratic formula is above.
You want each equation in standard form: ax^2 + bx + c = 0
I begin each problem by defining variables.
For instance 3. Is in standard form. X^2 -2x - 3 = 0. a = 1, b = -2, c = -3
Now use quadratic formula: x = [- b + or - sqrt(b^2 - 4ac)]\2a
Answer:
y=x+6
Step-by-step explanation:
I think what you mean is:

Then using our rules of exponents, this is the same as
