Question

(X-1)squared
Expand and simplify

Answer 1

Answer:

Step-by-step explanation:

(a - b)² = a² -2ab + b²

Here, a = x and b = 1

(x -1)² = x² - 2 * x *1 + 1²

        = x² - 2x + 1

Answer 2

$\sf \longmapsto \:( x + 1) {}^{2}$

$\sf \longmapsto(x+1)(x+1)$

$\sf \longmapsto(x)(x)+(x)(1)+(1)(x)+(1)(1)$

$\sf \longmapsto \: x {}^{2} +x+x+1$

$\sf \longmapsto \: x {}^{2} +2x+1$

$\boxed{ \boxed{ \red {\sf x {}^{2} +2x+1}}}$
