What is the value of (4 + a) (4 - b) when a = 4 and b = - 4?
What is the value of (4 + a) (4 - b) when a = 4 and b = - 4?
Explanation
To find the value of (4 + a)(4 - b), substitute a = 4 and b = -4:
(4 + 4)(4 - (-4))
= (8)(8)
= 64
To find the value of (4 + a)(4 - b), substitute a = 4 and b = -4:
(4 + 4)(4 - (-4))
= (8)(8)
= 64
