Answer:
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x=−1±√61/6
x≈1.13504161,−1.46837494
Explanation:
3x2+x−5=0
Step 1: Use quadratic formula with a=3, b=1, c=-5.
x=−b±√b2−4ac/2a
x=−(1)±√(1)2−4(3)(−5)/2(3)
x=−1±√61/6
x=−1/6+1/6√61 or x=−1/6+−1/6√61
