This is an incomplete quadratic equation. Drop the 0X, as it is superfluous.
4X^2 -25 = 0
X^2 =25/4
X = +/- sqrt(25/4)
X = +/- (5/4)
check
4(5/4)^2 -25 = 0
true
4(-5/4)^2 - 25 = 0
also true
It's not enough to copy the question off the test. If you don't tell us what the trinomial is, we can't factor it for you.
In algebra, the factor theorem is a theorem linking factors and zeros of a polynomial. It is a special case of the polynomial remainder theorem.The factor theorem states that a polynomial has a factor if and only if
If you mean: 2x2+7x+5 then it is (2x+5)(x+1) when factored
Factor it once, and then factor the factors.
just like factoring any other trinomial.
(x+8)(x-5)
(x + 2)(x - 9)
(x + 8)(x - 5)
(5x - 1)(x + 6)
-70
(x + 2)(x - 8)
(5x + 2)(x + 1)
-((x + 2)(x - 9))
(x - 3)(x + 6)
(X+9)(x-2)
(x + 2)(x - 7)
-70
