Question from John, a student: Solve each equation. Check each solution. 10/2y+8 - 7y+8/y(squared)-16 = -8/2y-8 |
Hi John,
Each of these problems require finding a common denominator, simplifying the expression and then solving the resulting equation. I'm going to illustrate with
Using the common denominator of x(x + 2) on the left side this simplifies to
7(x + 2) + x(3x) = 4x(x + 2)
-x2 - x + 14 = 0
Solving this using the general quadratic gives me
x = 1/2 (-1 ± √65)
Now try your problems,
Harley
