Factor x^3 -4x^2 -3x +18 =0
earnstyle [38]

Answer:

none of the above

Step-by-step explanation:

A graphing calculator shows the zeros to be x=-2, and a double zero at x=3. Hence the factorization is ...

(x +2)(x -3)^2 = 0

The premise that 4 is a zero is incorrect, and none of the answer choices include (x+2) as a factor. The problem is unworkable as written here.

For what values of m does the graph of y 3x2 7x m have two x intercepts
Phoenix [80]

The graph has a minimum point and is a parabola. Therefore, change the minimal value in the formula y = 3x2 + 7x + m. The value at the minimum point must be smaller than zero because the graph has two x-intercepts. The minimum point of the graph, which is a parabola, lies at x=-b/2a = -7/6.

What is Graph?

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.

The graph has a minimum point and is a parabola.

Therefore, change the minimal value in the formula y = 3x^2 + 7x + m.

The value at the minimum point must be smaller than zero because the graph has two x-intercepts.

The graph is a parabola, with x=-b/2a = -7/6 as the minimum.

3(49/36) – 49/6 + m < 0

49/12 – 49/6 + m < 0

(49-98)/12 + m < 0

-49/12 + m < 0

m < 49/12
