Question:
Find the square of (X-3) (X-3)
Answer:
Square the following,
(x-3) (x-3)
is the same as,
(x - 3)²
using the form,
(a-b)² = a² - 2ab + b²
we can expand our given as,
(x-3)² = (x)² - 2(x)(3) + (3)²
(x-3)² = x² - 6x + 9
Proof using FOIL method,
(x-3) (x-3)
x² - 3x - 3x + 9
x² - 6x + 9
[tex]\therefore \;\large\boxed{\text{\sf The answer is $\sf x^2 - 6x + 9$}}[/tex]
