do u knw the vertex form ?

anonymous · Answer

No I'm confused

ganeshie8 · Answer

vertex form :-

$\large   a(x-h)^2 + k$

anonymous · Answer

Okay I get that but how do you get the answer

ganeshie8 · Answer

$\large   x^2+4x -3 $

$\large   x^2+2 \times  2 x  -3 $

ganeshie8 · Answer

$\large   x^2+4x -3 $

$\large   x^2+2 \times  2 x  -3 $

$\large   x^2+2 \times  2 x + 4  - 4 -3 $

ganeshie8 · Answer

$\large   x^2+4x -3 $

$\large   x^2+2 \times  2 x  -3 $

$\large   x^2+2 \times  2 x + 2^2  - 4 -3 $

ganeshie8 · Answer

$\large   x^2+4x -3 $

$\large   x^2+2 \times  2 x  -3 $

$\large   x^2+2 \times  2 x + 2^2  - 4 -3 $

$\large  (x+2)^2 - 7 $
