Answer:
5sqrt2 or -5sqrt2(It might not make sense because I couldn't really do everything on this platform but it is right)
Explanation:
Step 1: Simplify both sides of the equation.
−x2+50=0
For this equation: a=-1, b=0, c=50
−1x2+0x+50=0
Step 2: Use quadratic formula with a=-1, b=0, c=50.
x= −b±√b2−4ac 2a
x= −(0)±√(0)2−4(−1)(50) 2(−1)
x= 0±√200 -2
x=−5√2 or x=5√2
