Calculation: 1 / (x ^ 2-7x + 10) + 1 / (x ^ 2-x-2) + 1 / (x ^ 2 + 5x + 4) + 1 / (x ^ 2 + 11x + 28) = () Detailed process

Calculation: 1 / (x ^ 2-7x + 10) + 1 / (x ^ 2-x-2) + 1 / (x ^ 2 + 5x + 4) + 1 / (x ^ 2 + 11x + 28) = () Detailed process


1/（x^2-7x+10)+1/(x^2-x-2)+1/(x^2+5x+4)+1/(x^2+11x+28)=[1/(x-5) -1/(x-2) + 1/(x-2) - 1/(x+1) + 1/(x+1)-1/(x+4) + 1/(x+4) - 1/(x+7)] /3=[1/(x-5) -1/(x+7)] /3



5x + 7x [14-x] = 28? What is x?


5x+7X[14-X]=28
5X＋98－7X＝28
7X－5X＝98－28
2X＝70
X＝35



7 out of 8 x 1 out of 2 = 9 out of 5


7 out of 8 x 1 out of 2 = 9 out of 5
7x of 8 = 1 of 2 + 9 of 5
7x of 8 = 28 of 10
x=3.2
