7,4(a+b)-6(a+b)^(2)

(-4/7 a^2 b)xx(-2/3 b^2c)xx(-7/6 c^2a)

If a^(2)+2b=7,b^(2)+4c=-7 and c^(2)+6a=-14, then thevalue of (a^(2)+b^(2)+c^(2)) is

5/4-7/6-(-2)/3=\ 3/4 (b) -3/4 (-7)/(12) (d) 7/(12)

If a^(4) + b^(4) = a^(2) b^(2) find a^(6) + b^(6)

Add the following 3a+6a^2b+4b,2b-9ab^2-6a,-6a-7b+2a^2b

Add : 6- 3a + b , a - 7-6b and 3b + 2- a.
