the given equation satisfies all real values except \(x=2,-12\) as we have in denominators \((x-12)(x-2)\) which would make equation undefined

i thought it worked out for all of them

it satisfies all values except \(x=2\) and \(x=-12\)

can u explain why?
mathmath333
  • mathmath333
because in the denominator u have \(x^2+10x-24=(x+12)(x-2)\) if u put \(x=2\) or \(x=-12\) the denominator will become zero and any number divide by zero is undefined.

is there an easier way to check the answer?

yes there is Set the denominator equal to zero and solve $$ x^2+10x-24=(x+12)(x-2)=0 $$ This helps you find values that x should NOT be Just be careful. Before you do this, just make sure that none of these terms is cancelled by the numerator.

You never want the denominator equal to zero.
