Answer:
5x²
Step-by-step explanation:
Make a column just with number on left side and the variables on the right side,
Like;
- Expression: Number || Terms
Each of the expression can be rewritten as:
40x² = 2*2*5*2 * x*x
5x³ = 5 * x*x*x*y
20x⁵y³= 2*2*5 * x*x*x*x*x*y*y*y
Here we see the greatest common number from the number row is 5(So it's a factor)and the greatest common term from the variables row is x*x = x² (So it's a factor of terms)
Now multiply the factors to get our GCD:
