Solve using quadratic formula 2x^2-64x+494=0

x = 19 or x = 13

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 - 64 x + 494 = 0

Divide both sides by 2:

x^2 - 32 x + 247 = 0

Subtract 247 from both sides:

x^2 - 32 x = -247

Add 256 to both sides:

x^2 - 32 x + 256 = 9

Write the left hand side as a square:

(x - 16)^2 = 9

Take the square root of both sides:

x - 16 = 3 or x - 16 = -3

Add 16 to both sides:

x = 19 or x - 16 = -3

Add 16 to both sides:

x = 19 or x = 13
