suppose that:

which real numbers have negative squares?

LOL, the non-negative property of even exponents has conquered me again. Thanks Deveno.

When findin the zeros for.

*Not possible to have square root of a negative number, hence

no real roots. Also if you graph the parabola for the above

Quad equation, you will see it is a transaltion of 6units vertically

up the yaxis, and the graph doesn't cut the xaxis; hence no solutions. - November 8th 2011, 10:03 AMBobBaliRe: No Real Solutions
