Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
1
1/2 = 25/50
(x + 2)(3x - 1)(3x + 1)
No
2(5x - 1)(3x - 2)
1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5
(x-1)(x+2)
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
x^2-x+1 cannot be factorised
2(x - 7)(x - 1)
That can be factored to (x - 2)(x - 1)
