Answer:

-54

Step-by-step explanation:

The greater numbers on a negative and positive scale are on the right side of the scale. The number 0 is in the middle of the scale. Numbers that are smaller than 0 are on the left side. Here's an example of a scale

-80________________________________80

-77 -64 -54 0 +54 +64 +77

Now, the number that is far from the 0 on the left side is the smallest. This would make -54 greater than -77.

$Rewrite the expression 6j^2 - 4j + 12$ in the form $c(j + p)^2 + q$, where $c$, $p$, and $q$ are constants. What is $\frac{q}{p}$$

The ratio of $\frac{q}{p}$ = - 34

How to solve such questions?

Such Questions can be easily solved just by some Algebraic manipulations and simplifications. We just try to make our expression in the form which question asks us. This is the best method to solve such questions as it will definitely lead us to correct answers. One such method is completing the square method.

Completing the square is a method that is used for converting a quadratic expression of the form $ax^{2} + bx + c$ to the vertex form

$a(x - h)^{2} + k$ . The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square: $a(x + m)^{2} + n$ , such that the left side is a perfect square trinomial
