What is the value of x ?
(1) x^3 = 6x − x^2
(2)14x = x^3 + 5x^2
x^3 = 6x - x^2
by factoring we have: x (x + 3) ( x - 2) = 0 so x = 0, x = - 3 and x = 2 (ins.)
14x = x^3 + 5x^2
by factoring we have: x (x + 7) (x - 2) = 0 so x = 0, x = -7 and x = 2 (ins.)
Statement (1) AND (remember in Mathematics "and" means intersection, in layman's term: what is the common in both statement?) Statement (2)
x = 0 as well as x = 2
So still insufficient because we have two values of x
Hope I helped
