we know the complex number has standard form a+ib
Inorder to find our answer ib^2 should.be 1
Ex:-
2-i
2:-

-4x^2-5x-15+x^2= -3x^2-5x-15 is the answer
Answer:
The correct answers is rectangle and square.
Answer:
x/6 = 4/5
x(5) = 6(4)
5x=24
x=24/5
Let me know if this helps!
This does not look easy to factor, so I'd suggest using the quadratic formula:
-1 plus or minus sqrt( 1-4(3)(-5) )
x = -----------------------------------------------
2*3
-1 plus or minus sqrt(61)
= ------------------------------------
6
Thus, there are 2 real, unequal, irrational roots / solutions.
