x^2 + 3
= x^2 - (-3)
= x^2 - 3i^2
= (x - i√3)(x + i√3)
x2 - 9x + 20 = (x - 4)( x - 5)
The expression 2x squared plus x squared can be simplified by combining like terms. When we add 2x squared and x squared, we get 3x squared. Therefore, the simplified expression is 3x squared.
2(5c + 2d)(5c + 2d)
35
It is a quadratic expression in the variable x.
(3t + 1)(t + 5)
You don't! There are no common factors.
(x + 5)(x + 1)
x(x + 23)
the answer is (3x-2)(9x squared+6x+4)
(x - 2)(2x - 3)
x2 + 6x + 8 =(x + 2)(x +4)
It can't be factored because the discriminant of this quadratic expression is less than zero.
this problem cannot be factored
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
All you can do to factor that expression is to divide both terms by y: y2 + 4y = y(y + 4)
If you mean (1+2x)2, that is already factored.
