Question

What is the value of the expression below when w=3w=3?

4w^2 -7w-8
4w
2
−7w−8

Answer 1

7 is the value

Explanation:

Given that,

→ w = 3

The given equation is,

→ 4w² - 7w - 8

Let's solve the problem,

→ 4w² - 7w - 8

→ 4(3)² - 7(3) - 8

→ 4(9) - 21 - 8

→ 36 - 29

→ [ 7 ]

Hence, the solution is 7.
