Respuesta :
C
given x² + 16x = 41
to complete the square on this equation
since the coefficient of the x² term is 1
add (half the coefficient of the x-term )² to both sides
x² + 2(8)x + 64 = 41+ 64
(x + 8 )² = 105 → C
Answer:
Option C is correct
Step-by-step explanation:
Given the equation
[tex]x^2+16x=41[/tex]
we have to find the equation results from completing the square.
For completing the square method, since the coefficient of [tex]x^2[/tex] is 1 therefore we have to divide the coefficient of x by 2 and then squaring of that value adding on both sides of equation, we get
Here coefficient of x is 16 therefore square of half the number adding both sides
[tex]x^2+16x+64=41+64[/tex]
[tex]x^2+8x+8x+64=105[/tex]
[tex]x(x+8)+8(x+8)=105[/tex]
[tex](x+8)(x+8)=105[/tex]
[tex](x+8)^2=105[/tex]
Option C is correct
