2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
If you mean: x squared -5x +6 then it can be factored as (x-2)(x-3)
X2 - 5X = 24 X2 - 5X - 24 = 0 (X - 8)(X + 3) X = 8 ----------------and X = - 3 --------------
The expression "5 times x squared" can be represented as 5x^2, where x is a variable representing an unknown value. This expression indicates that the variable x is squared (multiplied by itself) and then multiplied by 5. The result of evaluating this expression will depend on the specific value assigned to x.
The factors of x2 + 5x + 4 would be (x + 1) and (x + 4)
-x2+2x
2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
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)
5(x2 + x + 1)
Assuming that x2 is x squared: (x - 9)(x + 4)
If you mean: x squared -5x +6 then it can be factored as (x-2)(x-3)

X2 - 5X = 24 X2 - 5X - 24 = 0 (X - 8)(X + 3) X = 8 ----------------and X = - 3 --------------
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
x2 - 5x = 0Factor the left side:x (x - 5) = 0x = 0x = 5
