x={-5,7}x={5,7}

Explanation:

We know that a^0=1a0=1 so making x^2-2x-35=0x22x35=0 the solutions are x={-5,7}x={5,7} but we know also that aa must be non null. Solving now

x^2 - 7 x + 11 =0x27x+11=0 we have x = 1/2 (7 pm sqrt[5]) ne {-5,7}x=12(7±5){5,7}

Finally the equation is meaningful for

x={-5,7}x={5,7}
