Question

23.
If (a - b) = -2, (b- c) = -4, (c- a) = 6, ab = 24, bc = 60 and ac = 40 (where a, b and care positive
numbers), then the value of (a - b+ c)2 + (a + b - c)2 + (-a + b + c)2
​

Answer 1

Step-by-step explanation:

• We get a=4
• b=6
• c=10
• 2{a-b+c+a+b-c-a+b+c}
• 2{a+b+c}
• 2(4+6+10)
• 2(20)
• 40
