Question

Please solve the following:

12(x^2–x–1)+13(x^2–x–1)=25(x^2–x–1)

364x–64x=300x

Answer 1

Infinite many solutions

Explanation:

When the expressions are simplified, the variables will disappear and a true statement like -25=-25 or 0=0 is left. This means that there are an infinite many of solutions to solve the equation.

Example: 364x-64x=300x

300x=300x

x=x

Any number substitute for x will satisfy the equation.
