16x( x - 2) = 8x + 25
16xx - 32x - 8x - 25 = 0
16x^2 - 40x - 25 = 0
Now factorize the above quadratic equation ...
16xx - 24x - 25 = 0
( x - 24) ( x + 1) = 0
The product of x with itself, what you have written as "xx", is "x squared", or "x^2". Has your class not covered exponents or multiplying polynomials yet?kldiggs said:16x( x - 2) = 8x + 25
16xx - 32x + 8x - 25 = 0
How did you arrive at this point? (The "16" is gone, etc, so many steps would appear to be missing.) It will be helpful if you could show all of your steps. Thank you.kldiggs said:( x - 24) ( x + 1) = 0
