Answer:
Step-by-step explanation:
The coefficients of the x terms are {1, 3, -3}, so the discriminant, b^2 - 4ac, is 3^2 - 4(1)(-3), or 9 + 12, or 21. The positive nature of the discriminant tells us that there are two real, unequal roots. Following the quadratic formula, we get:
-3 ± √21
x = -----------------
2
Answer:
Step-by-step explanation:
You are dividing x by 5 and then subtracting 4.
All you have to do is add exponents when multiplying like monomials. So it's just 4^2
Plug in the values
3(5) - 5(1)
15 - 5 = 10
Solution: 10
