Let <em>y</em> = √(<em>x</em> - 10), so that <em>y</em>² = <em>x</em> - 10.
Then <em>x</em> = <em>y</em>² + 10 so that √<em>x</em> = ±√(<em>y</em>² + 10).
So we've rewritten the equation as
<em>y</em> = ±√(<em>y</em>² + 10)
In either case, squaring both sides gives
<em>y</em>² = <em>y</em>² + 10
and eliminating <em>y</em>² gives us the false result
0 = 10
so there is no solution.

Answer:
Step-by-step explanation:
x^2 - 10x + 29
x^2 - 10x = -29
x^2 -10x + 25 = -29 + 25
(x - 5)^2 = -4
(x - 5)^2 + 4 <==
The answer is ............................a
You move to the right, so the exponent is gonna be negative.
1.21 * 10-²
