Question

What is the value of the expression below when w=3
3w to the second power minus 6w minus 4

Answer 1

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.
