Answer:
Step-by-step explanation:
All real numbers are solutions in both.
12(x2−x−1)+13(x2−x−1)=25(x2−x−1)
Step 1: Simplify both sides of the equation.
25x2−25x−25=25x2−25x−25
Step 2: Subtract 25x^2 from both sides.
25x2−25x−25−25x2=25x2−25x−25−25x2
−25x−25=−25x−25
Step 3: Add 25x to both sides.
−25x−25+25x=−25x−25+25x
−25=−25
Step 4: Add 25 to both sides.
−25+25=−25+25
0=0
