If x = 3, what is the value of 2x^2 + 3x - 5?

If x = 3, what is the value of 2x^2 + 3x - 5?

Step 1: Start with the expression 2x^2 + 3x - 5.
Step 2: Substitute x = 3 into the expression. This means wherever you see x, you replace it with 3.
Step 3: The expression now looks like this: 2(3^2) + 3(3) - 5.
Step 4: Calculate 3^2, which is 9. So now the expression is 2(9) + 3(3) - 5.
Step 5: Now calculate 2(9), which is 18. The expression is now 18 + 3(3) - 5.
Step 6: Calculate 3(3), which is 9. The expression is now 18 + 9 - 5.
Step 7: Now add 18 and 9, which gives you 27. The expression is now 27 - 5.
Step 8: Finally, subtract 5 from 27, which gives you 22.
