Question

Solve the equation b^2+36=0 (not 6i)

Answer 1

I hope this helps you

b^2= - 36

b^2= - 1.6^2

b^2= i^2.(+,-6)^2

b=6i

b= - 6i

or b isn't real number there is no solution....

Answer 2

Answer:  ±6i

Step-by-step explanation:

$b^2+36=0\\\\b^2\qquad =-36\\\\\sqrt{b^2}\quad =\sqrt{-36}\\\\|b|\qquad =\sqrt{-1\cdot 6 \cdot 6}\\\\|b|\qquad =6i\\\\\large\boxed{b \qquad=\pm 6i}$
