Quadratic formula is x=(-b+-sqrt(b^2-4ac))/(2a)
a= 1, b=-4, and c=3
Therefore, x=(-(-4)+-sqrt((-4)^2-4(1)(3))/(2(1))
Solve for both the plus and minus equations; the answers will be the roots to the quadratic equation.
2 3/4 = 11/4 <=== written as an improper fraction
He started with 3.
3 X 3 = 9.
9 - 5 = 4.
4 X 4 = 16.
16 - 7 = 9.
9 divided by 3 = 3.
3 + 6 = 9.
Answer:
21/3 i think
Step-by-step explanation:
