What is the value of the expression below when w=3
3w to the second power minus 6w minus 4
To find the value of the expression when w=3, we substitute w=3 into the expression and simplify:
3w^2 - 6w - 4
= 3(3)^2 - 6(3) - 4
= 3(9) - 18 - 4
= 27 - 18 - 4
= 9 - 4
= 5
Therefore, when w=3, the value of the expression is 5.
To find the value of the expression when w=3, substitute w=3 into the expression and simplify:
Step 1: Substitute w=3 into the expression:
3w^2 - 6w - 4 becomes 3(3)^2 - 6(3) - 4
Step 2: Simplify:
3(9) - 18 - 4 becomes 27 - 18 - 4
Step 3: Continue simplifying:
27 - 18 - 4 becomes 9 - 4
Step 4: Final calculation:
9 - 4 equals 5
Therefore, when w=3, the value of the expression 3w^2 - 6w - 4 is 5.
