start by isolating the variable on one side by adding 43w^2 to both sides. the equation will read:
25w^2+5=0
*subtract 5 from both sides*
25w^2=-5
*divide both sides by 25*
w^2=-1/5
*take the square root of both sides*
w=√(-1/5)
the square root of -1 is i. the square root of 5 remains √5
the answer is i/√5.
hope this
