The difference of the square of a number and 12 is equal to 4 times that number. find
the negative solution.

-2

Step-by-step explanation: Let the unknown number be " a"

From the statement,

a^2 - 12 = 4a this is a quadratic equation

i.e  a^2 - 4a - 12 = 0

factorizing the quadratic expression

( a + 2 ) ( a - 6 ) = 0

i.e a = -2 or 6

so, the negative solution is -2

1 1/5
