Find a2 – b2 when a + b = 4 and
a – b = 6:
a) 10
b) 24
c) 18
d) 30
Explanation: To find the value of a² - b² when a + b = 4 and a - b = 6, we can use the identity:
a² - b² = (a + b)(a - b)
Given that a + b = 4 and a - b = 6, we can substitute these values into the identity:
a² - b² = (4)(6) = 24
Therefore, the value of a² - b² is: b) 24
