The difference of the square of a number and 28 is equal to three times that number find the negative solution

bazaltina [42]

Answer:

The negative solution = x = -4

Step-by-step explanation:

Let the number be = x

The square of number = x²

The difference between the square of a number and 28 = x²-28

Given that the difference of the square of a number and 28 is equal to three times that number.

Thus, the equation becomes

$x^2-28=3x$

subtract 3x from both sides

$x^2-28-3x=3x-3x$

$x^2-3x-28=0$

$\left(x+4\right)\left(x-7\right)=0$

$x+4=0\quad \mathrm{or}\quad \:x-7=0$

$x=-4,\:x=7$

Thus, the negative solution = x = -4
