is.
solution
of
the equation
mx2-x-2=0

Answer 1

Answer:

Equation:

Solution for mx^2-X+2=0 equation:

Simplifying

mx2 + -1X + 2 = 0

Reorder the terms:

2 + -1X + mx2 = 0

Solving

2 + -1X + mx2 = 0

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -1X + -2 + mx2 = 0 + -2

Reorder the terms:

2 + -2 + -1X + mx2 = 0 + -2

Combine like terms: 2 + -2 = 0

0 + -1X + mx2 = 0 + -2

-1X + mx2 = 0 + -2

Combine like terms: 0 + -2 = -2

-1X + mx2 = -2

Add '-1mx2' to each side of the equation.

-1X + mx2 + -1mx2 = -2 + -1mx2

Combine like terms: mx2 + -1mx2 = 0

-1X + 0 = -2 + -1mx2

-1X = -2 + -1mx2

Divide each side by '-1'.

X = 2 + mx2

Simplifying

X = 2 + mx2
