f(x) - g(x)
=> (3x² + x - 3) - (x² - 5x + 1)
=> 3x² + x - 3 - x² + 5x - 1
=> 3x² - x² + x + 5x - 3 - 1
=> 2x² + 6x - 4
1-4(u-1)
= 1- 4*u -4*(-1) (distributive property)
= 1 -4u+ 4
= -4u+ (1+4)
= -4u+5
Final answer: -4u+5~
The answer is K. It’s K because when you add all the numbers together it’s A.
The top one and bottom one
