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

Step-by-step 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
