Answer:
(2,√21)
Step-by-step explanation:
The circle centered at the origin has equation:
Any point that satisfies this equation lie on this circle.
When x=2, we substitute and solve for y.
Take square root to get:
Therefore (2,-√21) and (2,√21) are on this circle.
From the options, (2,√21) is the correct answer
<em><u>Solution:</u></em>
Given that,
We have to expand the brackets
<em><u>Use distributive property,</u></em>
a(b + c) = ab + bc
Multiply the number in front of parenthesis with each term inside the parenthesis and then add them together
