​

Answer 1

Respuesta:

x=6+√17 or x=6−√17

Explicación paso a paso:

(x−8)(x−4)=13

Step 1: Simplify both sides of the equation.

x2−12x+32=13

Step 2: Subtract 13 from both sides.

x2−12x+32−13=13−13

x2−12x+19=0

For this equation: a=1, b=-12, c=19

1x2+−12x+19=0

Step 3: Use quadratic formula with a=1, b=-12, c=19.

x=

−b±√b2−4ac

2a

x=

−(−12)±√(−12)2−4(1)(19)

2(1)

x=

12±√68

x=6+√17 or x=6−√17
