Answer:
2(x - 2)² - 7
Step-by-step explanation:
2x² - 8x + 1 ( factor out 2 from the first 2 terms )
= 2(x² - 4x) + 1
using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 4x
= 2(x² + 2(- 2)x + 4 - 4) + 1
= 2(x - 2)² - 8 + 1
= 2(x - 2)² - 7
Answer- 2(x-2)²-3
Step-by-step explanation:
Greetings !
given expression
[tex]2x {}^{2} - 8x + 1[/tex]
Thus, when you change it in the form of
[tex]a(x + b) {}^{2} + c[/tex]
we get the expression as
[tex]2(x -2 ) {}^{2} - 3 \\ [/tex]
simplify it and we get it as
[tex]2(x - 2) {}^{2} - 3 \\ 2(x {}^{2} - 4x + 4) - 3 [/tex]
Hope it helps!
distribute and multiply
[tex]2x {}^{2} - 8x + 4 - 3 \\ 2x { }^{2} - 8x + 1[/tex]
