How many complex roots does the equation 0=2x3−4x2−x+1 have?

3 complex solutions/roots

Step-by-step explanation:

You find the complex solutions by combining the expressions and isolating the variable x. The roots are known as the x values when the graph intersects the x-axis; Therefore, replace y with 0 then solve for x.

x = -0.55138752

x = 0.42681725

x = 2.12457026

Three complex roots. Check out the pic i attached.

Step-by-step explanation:

I took the quiz.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
