Find all the whole values of a for which the solution of the equation ax = 6 is a whole number.

ANSWER



EXPLANATION

The given equation is



Divide both sides by



Cancel out common factors on the left hand side,



For this solution to be a whole number, then should be a factor of
.

The reason is that, factors of 6 will divide exactly in to 6 without a remainder, making the answer a whole number.

The whole numbers that are factors of 6 are,



Note that, the set of whole numbers are,

Aquadratic function is one of the form f(x)=ax2 + bx + c l, where a,b, and c are numbers with are not equal to zero.

Y=-3x is the correct answer
