5 over x-3 minus 3 over x+2

St

So, if second denominator is "x + 2" , then 3/x - 5/(x+2)  

   3            5      

 ——  –  ————  =        

   x          x + 2  

the LCD is  x(x + 2)

  3(x + 2)            5x    

—————  –  —————  =  

  x(x + 2)         x(x + 2)  

 3x + 6 – 5x  

—————— =  

   x2 + 2x  

   6 – 2x  

—————  

  x2 + 2x

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer: c i think
