Answer 1

Using the quadratic formula, the values in the form a + bi is 1 + 4i.

What do we mean by quadratic formula?

• The quadratic formula is a formula used to solve quadratic equations in elementary algebra.
• There are alternatives to using the quadratic formula to solve quadratic equations, including factoring, completing the square, graphing, and others.
• Quadratic formula: $D = \frac{-b+-\sqrt{b^{2}-4ac } }{2a}$

So, represent in the form a + bi:

Given equation: $\frac{4+\sqrt{16 - (4)(5)} }{2}$

• From the equation, we can assume that the value of b is 4 and the value a must be 1.
• When the value of a will be 1, then only the denominator can be 2 as 2(1) = 2.

Hence, 1 + 4i.

Therefore, using the quadratic formula, the values in the form a + bi is 1 + 4i.
