If x, y, z are the three factors of a3 -7a - 6, then value of x+y+z will be Options:
If ax+by = 1 and bx + ay = 2ab/a2+b2 then (x2+y2)(a2+b2) is equal to
If a + 1/b = b+1/c = c+1/a (where a≠b≠c),then abc is equal to
If a = 1/a-5 (a>0), then the value of a + 1/a is
If x = 11, the value of x5- 12x4+ 12x3- 12x2 + 12x - 1 is
