(x-4)^2=36
take square roots,
± (x-4) =6
=>
x-4=6 => x=10
-(x-4)=6 => x-4 = -6 => x=-2
24.56m. your problem should look like a^2+29^2=38^2. you the. have a^2+841=1444. you subtract 841 from 1444 and are left with 603. < this is a^2. you take the square root of that and get 24.56
The parabola goes down(makes a sad face) because it is negative. The answer is 0,0
