write the solution set of the equation X² + X – 2 =0 is roster form .write the following set is the roster form
A={x:x€ R,2x+11=15}
B={x|x²=x,x€R}
C={x|x is a positive factor of a prime number p}
if Y={x|x is positive factor of the number 2p-¹(2p-1), where 2p-1 is a prime number. write Y in the roster form​

solve the following linear equations:
a)x/2+x/3+x/4=13
b)(x+2)(x+3)+(x-3)(x-2)-2x(x+1)
c)(2x-1)/3-(6x-2)/5=1/3
