Question

Solve the quadratic equation 3x squared + x -5=0 give your answer to 2 dp

Answer 1

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
