Given the numerical statement:
2(x-3) square - 3(x+1)square
Solution:
This can be written as,
2( x - 3)^2 - 3 (x + 1)^2
In order to have the simplified answer, we first square the values inside the parentthesis,then multiply it with its corresponding coefficient.
= 2( x - 3)^2 - 3 (x + 1)^2
= 2 ( x^2 - 6x + 9) - 3(x^2 + 2x + 1)
= 2x^2 - 12x + 18 - 3x^2 - 6x - 3
= -x^2 - 18x - 15
Final answer:
= -x^2 - 18x - 15
