Project #1
In solving quadratic equivalences came from India. I result be using the 6 step method to operate an equation. The equation is Xsquared + 4x-10.
a) My first step is to move the constant to the new(prenominal) side; Xsquared + 4X =10.
b) Second step is to multiply 4 times the coefficient; 4Xsquared + 16X = 40
c) Square the coefficient and add to both sides; 4Xsquared + 16X + 9= 40+9
d) manoeuvre the square Root of both sides; 4xsquared + 16X + 9=49
e) Set the leftfield side of the equation to the positive square root and put to work for X; 2x +3=+_ 7
f) Checking my work yielded these answers;
2x + 3 = 7 2X + 3 =-7
2x = 4 2x = -10
X = 2 x = -5
The solution to the equation is 2 and -5.
Project #2
Using the formula given from rapscallion 331; Xsquared X +41. Per directions we are to select 5 numbers racket, twain odd, dickens even, and the number 0. The numbers chosen are (0,4,6,9, and 15). To solve for 0; xsquared x +41 is 0-0+41 = 41. Solve for 4; 16 -4 +41 = 53. Solve for 6; 36-6+4=34. Solve for 9; 81 -9 + 41= 113. Solve for 15; 225 15 + 41 = 251. All of these numbers are prime numbers, all numbers that I substituted did not yield any composite numbers. heterogeneous by definition are numbers with more than two factors.
