4x^2 + 20 = 0; TAKING SQUARE ROOTS
1 answer:
Answer:
<u>x₁ = i√5</u>
<u>x₂ = -i√5</u>
Step-by-step explanation:
Let's solve the equation using square roots.
4X^2 + 20=0
x² + 5 = 0 (Dividing by 4 at both sides of the equation)
x² = -5 (Subtracting 5 at both sides of the equation)
√x² = √-5 (Square root to both sides of the equation, √-1 = i)
x = +/- i√5 ( (Roots of the solution)
<u>x₁ = i√5</u>
<u>x₂ = -i√5</u>
