Step-by-step Answer:

Step 1:

Extract factor(s) common to all terms.

In this case, the HCF is 3, so the expression is written

-12x^2+45x+12 = -3(4x^2-15x-4)

The negative sign was also exrracted to give a positive leading coefficient, which is easier to work with.

Step 2, group the coefficient in such a way that there is a common factor.

Leaving the factor -4 for the moment, and concentrate on the coefficients in parentheses, write the original expression as

4x^2 - 15x -4  

= 4x^2 -16x

          +   x -4

= 4x*(x-4) + 1*(x-4)

extract (x-4) as a common factor

= (x-4)(4x+1)

Step 3:

Combine all the factors to get

-3(x-4)(4x+1)

=3(4-x)(4x+1)

as the complete factoring of the given expression.

Answer:

  -0.16

Step-by-step explanation:

The 'a' value can be found by looking at the difference between the y-value of a point 1 unit from the vertex, and the y-value of the vertex.

Here, that is a negative fraction of a unit. If we assume the value is a rational number that can be accurately determined from this graph, then we can find it by looking for a point where the graph crosses a grid intersection. It looks like such grid points are (-7, 0) and (3, 0). The vertex is apparently (-2, 4), so the vertex form of the equation is ...

  y = a(x +2)^2 +4

Using the point (3, 0), we have ...

  0 = a(3 +2)^2 +4 . . . . . fill in the values of x and y

  -4 = 25a . . . . . . . . . . subtract 4; next, divide by 25

  a = -4/25 = -0.16

Please answer as fast as possible thanks

The correct answer is the 2nd choice because -1/6 is closer to 0 and the surface of the pool would be considered 0. -4/6 is farther away from 0 so it is less.
