x2 + 5x + 6 = 0
(x + 3)(x + 2) = 0
So x + 3 = 0 or x + 2 = 0
So x = -3 or x = -2
It is, as stated, x2 - 5x + 25/4 = 0
-15x2+5x=-5x(3x-1)
(5x + 2)(x + 3)
-x2+2x
(x - 1)(5x + 7)
If: x^2 -5x +6 = 0 then x = 2 or x = 3
It is, as stated, x2 - 5x + 25/4 = 0
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
x^(2) + 5x^(2) = 6x^(2) Think of it as 2 + 5(2) = 6(2) ( 2 + 10 = 12 = 6(2)) Note : You just add the coefficients(numbers)/. However, be careful and note the difference for multiplication. x^(2) X 5x^(2) = 5x^(4) ( That is 'five 'x' to the fourth power'). In this case x^(2) means x X x and 5x^(2) = 5 X x X x , so on multiplication it becomes 5 X x X x X x X x = 5x^(4)

-15x2+5x=-5x(3x-1)
5x2+56xy+11y2 = (5x+y)(x+11y) when factored
(5x + 2)(x + 3)
5(x2 + x + 1)
It is: 25+64 = 89
The given expression can be simplified to: 8x squared +9
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
