Solve x2 + 3x + 4 = 0 using the Quadratic Formula. Select any solutions that apply.

x=−3±i√72x=-3±i72

Step-by-step explanation:

Write the problem as a mathematical expression.

x2+3x+4=0x2+3x+4=0

Use the quadratic formula to find the solutions.

−b±√b2−4(ac)2a-b±b2-4(ac)2a

Substitute the values a=1a=1, b=3b=3, and c=4c=4 into the quadratic formula and solve for xx.

−3±√32−4⋅(1⋅4)2⋅1-3±32-4⋅(1⋅4)2⋅1
