Question

Use the quadratic formula to find the roots of the equation. Round to tenths place if necessary.

11x^2 - x - 3 = 0
A. {-1, 1.2}
B. {-11, 13.2}
C. {-0.5, 0.6}
D. no real solution

Answer 1

x=(-b+sqrt(b^2-4ac))/(2a)

Answer 2

and x=(-b-sqrt(b^2-4ac))/(2a)

Answer 3

b=-1, a=11, c=-3
so
x=(-(-1)+sqrt((-1)^2-4(11)(-3))/(2(11))=.56
x=(-(-1)-sqrt((-1)^2-4(11)(-3))/(2(11))=-.47
