(i) (3x - 1)^2 – (3x - 2) (3x + 1)
Answers
Step-by-step explanation:
(3x-1)^2 - (3x-2)(3x+1)
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3
or....
(3x-1)^2 - (3x-2)(3x+1)
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,in that case we can find the solution of this equation by
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,in that case we can find the solution of this equation by-3x + 3 = 0
(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,in that case we can find the solution of this equation by-3x + 3 = 0x = 1
