R-5h=Hr+2h solve for r

The solution to this equation could not be determined.

Step-by-step explanation:

Simplifying

r + -5h = hr + 2h

Reorder the terms:

-5h + r = hr + 2h

Reorder the terms:

-5h + r = 2h + hr

Solving

-5h + r = 2h + hr

Solving for variable 'h'.

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

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

-5h + -2h + r = 2h + -2h + hr

Combine like terms: -5h + -2h = -7h

-7h + r = 2h + -2h + hr

Combine like terms: 2h + -2h = 0

-7h + r = 0 + hr

-7h + r = hr

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

-7h + -1hr + r = hr + -1hr

Combine like terms: hr + -1hr = 0

-7h + -1hr + r = 0

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

-7h + -1hr + r + -1r = 0 + -1r

Combine like terms: r + -1r = 0

-7h + -1hr + 0 = 0 + -1r

-7h + -1hr = 0 + -1r

Remove the zero:

-7h + -1hr = -1r

Combine like terms: -1r + r = 0

-7h + -1hr + r = 0

The solution to this equation could not be determined.

Step-by-step explanation:

Given

Solving for r:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
