x²+2x+1=
a²-6a+9=
x²+20x+100=
n²-10n+25=
y²-22y+121=
x²-16x+64=

Answer 1

x² + 2x + 1
x² + x + x + 1
x(x + 1) + (x + 1)
(x + 1)(x + 1)
(x + 1)²

__________

a² - 6a + 9
a² - 3a - 3a + 9
a(a - 3) - 3(a - 3)
(a - 3)(a - 3)
(a - 3)²

__________

x² + 20x + 100
x² + 10x + 10x + 100
x(x + 10) + 10(x + 10)
(x + 10)(x + 10)
(x + 10)²

__________

n² - 10n + 25
n² - 5n - 5n + 25
n(n - 5) + 5(n - 5)
(n - 5)(n - 5)
(n - 5)²

__________

y² - 22y + 121
y² - 11y - 11y + 121
y(y - 11) + 11(y - 11)
(y - 11)(y - 11)
(y - 11)²

__________

x² - 16x + 64
x² - 8x - 8x + 64
x(x - 8) + 8(x - 8)
(x - 8)(x - 8)
(x - 8)²
