solve 56 66a

answer for one is 2 solutions

modulus sign doesnt matter

so solve the quadratic

x^2+x-2=0

for second 3 solutions x=2 ,x=1,x=-1

x2+x+1=-3..........(1)
x2+x+1=3....(2)

now solve the eqns...first gives non-real roots

why modulus sign doesnt matter?

@avinav that modulus sign doesnt matter as any how the expression inside modulus is always +ve...........
