Question

Use the quadratic formula to solve the equation 5x^2 - 7x - 3 = 0 .

Select one:
a. x=(7+sqrt(109))/10 and x=(7-sqrt(109))/10
b. x=(7+sqrt(11))/10 and x=(7-sqrt(11))/10
c. No solution
d. x=(-7+sqrt(109))/10 and x=(-7-sqrt(109))/10

Answer 1

\[x = \frac{ -b \pm \sqrt{b^2 - 4(a)(c)} }{ 2a }\]
Gather your values of a,b, and c.
Using the standard form as a reference.
\[ax^2 + bx + c = 0\]
and then evaluate.

Answer 2

Soo 5x^2-7x+3=0

Answer 3

you add 5 and 2?
