Solution

We have given,
$(2 x - 3)^{2} - 8 x + 12$
$= (2 x^{2} - 6 x + 9 - 8 x + 12)$
$= 2 x^{2} - 14 x + 21$
This is the standered form as:
$a x^{2} + b x + c$

Factorise:
$(2 x - 3)^{2} - 8 x + 12$

(3 + 5 x + 7 x^{2} + 9 x^{3})

+ (4 + 2 x - 3 x^{2} - 8 x^{3})

\sqrt{3} y = 2 x

(2 x + 3)^{2} + (2 x - 3)^{2} = (8 x + 6) (x - 1) + 22

- 4 (8 x - 10) - 3 (7 x - 1) + 3 (4 x) + 12
