Question

What are the roots, in simplest form, of the equation 4x2 + 98= 0

Answer 1

x = ±√ 24.500 = ± 4.94975

Explanation:

: (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Answer 2

Explanation:

4x² + 98 = 0

2x² + 49 = 0

2x² = -49

x² = -49/2

x = ±√(-49/2)

x = ±7i√(1/2)

x = (±7i√2) / 2
