Will award brainliest with math ive been asking for hours! ! 1) solve the following equation by identifying all of its roots including all real and complex numbers. in your final answer, include the necessary steps and calculations. hint: use your knowledge of factoring polynomials. (x^2 + 1)(x^3 + 2x)(x^2 - 64) = 0 2) solve for the roots of x in each of the equations below. x^4 - 81 = 0 x^4 + 10x^2 + 25 = 0 x^4 - x^2 - 6 = 0 3) solve for the roots in the equation below. x^4 + 3x^2 - 4 = 0

For 1 its 
x^2 + 1 = 0
x^2 = -1
x = 
x = i
:
(x^3 + 2x) = 0
Factor out x
x(x^2 + 2) = 0
x = 0
