Solve. x² + 20x + 100 = 50 a)x=−10±52√ b)x=50±252√ c) x=10±52√ d)x=50±52√

x = −10 ± 5√2

Solve. x²+ 20x + 100 = 50

Subtracting 50 from both sides

To solve the quadratic equation, let us use quadratic formula

For, ,

So, a=1, b=20, c=50

So, we get,

x=

Option(a) Answer

So, x=-10+5

or, x=-10-5
