Write the equation 2x 2 - 4x + 6 = 1 in standard form and then choose the value of "c." 5 3 2.5

Option 1. 5 is the correct option.

Step-by-step explanation:

Since we know the standard form of a polynomial is ax²+bx +c =0

So we have to transform the given equation 2x²-4x+6 =1 in the standard given as above.

2x² - 4x + 6 = 1

2x² - 4x + 6 - 1 = 0

2x² - 4x + 5 = 0

Now this is the standard form of the equation.

Here constant term c = 5.

Therefore Option 1. c = 5 is the correct option.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
