Answer:
5/8
Step-by-step explanation:
Step 1 :
53x3 - 8
Step 2 :
Trying to factor as a Difference of Cubes:
2.1 Factoring: 125x3-8
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0+b3 =
a3+b3
Check : 125 is the cube of 5
Check : 8 is the cube of 2
Check : x3 is the cube of x1
Factorization is :
(5x - 2) • (25x2 + 10x + 4)
Trying to factor by splitting the middle term
2.2 Factoring 25x2 + 10x + 4
The first term is, 25x2 its coefficient is 25 .
The middle term is, +10x its coefficient is 10 .
The last term, "the constant", is +4
Step-1 : Multiply the coefficient of the first term by the constant 25 • 4 = 100
Step-2 : Find two factors of 100 whose sum equals the coefficient of the middle term, which is 10 .
-100 + -1 = -101
-50 + -2 = -52
-25 + -4 = -29
-20 + -5 = -25
-10 + -10 = -20
-5 + -20 = -25
For tidiness, printing of 12 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(5x - 2) • (25x2 + 10x + 4)
Answer:
follow the steps bellow
Step-by-step explanation:
since you already have the x values it is easier,once you have the the y values you are going to plot the point the left side of the table are the x values and the right side are the y values. X values on a graph is the horizontal line or the line that goes left to right, and the y values on the graph re the line that goes vertical or up and down.
