Answer:

product will 127xsquare

sum will 99x

prime factors of 127-

so xsquare +99x+11square+6

so now product will 11

wo solutions were found :

x =(-99-√9293)/2=-97.700
x =(-99+√9293)/2=-1.300
Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2".

Step by step solution :

Step 1 :

Trying to factor by splitting the middle term

1.1 Factoring x2+99x+127

The first term is, x2 its coefficient is 1 .
The middle term is, +99x its coefficient is 99 .
The last term, "the constant", is +127

Step-1 : Multiply the coefficient of the first term by the constant 1 • 127 = 127

Step-2 : Find two factors of 127 whose sum equals the coefficient of the middle term, which is 99 .

-127 + -1 = -128
-1 + -127 = -128
1 + 127 = 128
127 + 1 = 128

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Equation at the end of step 1 :

x2 + 99x + 127 = 0
Step 2 :

Parabola, Finding the Vertex :

2.1 Find the Vertex of y = x2+99x+127

Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is -49.5000

Plugging into the parabola formula -49.5000 for x we can calculate the y -coordinate :
y = 1.0 * -49.50 * -49.50 + 99.0 * -49.50 + 127.0
or y = -2323.250
