A positive real number is 1 more than another. When -2 times the smaller is added to the square of the larger, the result is 33.
Naya [18.7K]

Answer:

The smaller number is 4√2 and the larger number is (4√2 + 1).

Step-by-step explanation:

Let the two numbers be <em>x </em>and <em>y</em>, where <em>y</em> is the larger of the two numbers.

Since <em>y</em> is the larger number, it is one more than the smaller number. So:

y=x+1

When negative two times the smaller is added to the square of the larger, the result is 33. In other words:

-2x+y^2=33

Substitute:

-2x+(x+1)^2=33

Solve for <em>x</em>. Square:

-2x+(x^2+2x+1)=33

Simplify:

x^2+1=33

Subtract one from both sides:

x^2=32

And take the square root of both sides:

x=\pm\sqrt{32}=\pm 4\sqrt{2}

Since <em>y</em> is positive, we can ignore the negative case. So, the smaller number is:

x=4\sqrt{2}\approx5.66

And the larger number is:

y = 4\sqrt{2} + 1 \approx6.66
