Question

If A = 1 + 3 + 5 + a) o +99; B = 2 + 4 + 6 + 8 + b) - 50 +100 then the value of A-B is c) - 100 d) - 150 +99: B=2 +100 then the value of A+B​

Answer 1

Answer:

Given- x=−2,y=3,z=1

So, x3+y3+z3−3xyz=(x+y+z)(x2+y2+z2−xy−yz−zx)

=(−2+3+1)((−2)2+(3)2+(1)2−(−6)−(−3)−(−2))

=(2)(4+9+1+6−3+2)

=(2)(19)
