$y = 50 x^{2} - 30 x + 5$ $color(blue)(y = 50x^2 - 30x + 5$ is the standard form.

$y = {(x - 1)}^{2} + {(7 x - 2)}^{2}$ $y = (x-1)^2 + (7x-2)^2$

$y = x^{2} - 2 x + 1 + 49 x^{2} - 28 x + 4$ $y = x^2 - 2x + 1 + 49x^2 - 28x + 4$

$y = 50 x^{2} - 30 x + 5$ $color(blue)(y = 50x^2 - 30x + 5$ is the standard form.

What is the standard form of y=(x−1)2+(7x−2)2y= (x-1)^2+(7x-2)^2 ?
