$y=4{\left(x-1\right)}^{2}+5$
$y=4\left(x-1\right)\left(x-1\right)+5$
$y=4\left({x}^{2}-2x+1\right)+5$
$y=4{x}^{2}-8x+4+5$
$y=4{x}^{2}-8x+9$

This equation in standart form shoul look like this $y=a{x}^{2}+bx+c;a\ne 0$
$y=4\left(x-1{\right)}^{2}+5$
$=4\left({x}^{2}-2x+1\right)+5$
$=4{x}^{2}-8x+4+5$
$=4{x}^{2}-8x+9$ - in standart form
