F(x) - g(x) = 9x^3 + 2x^2 - 5x + 4 - (5x^3 - 7x + 4)
f(x) - g(x) = 9x^3 + 2x^2 - 5x + 4 - 5x^3 + 7x - 4
f(x) - g(x) = 4x^3 + 2x^2 + 2x ....combine like terms
f(x) - g(x) = 2x(2x^2 + x + 1) ...factor

One of the roots of the equation x²-5x +q=0 is 2. Find the other root and the value of the coefficient q.

yuradex [85]

Answer:

Other root: $x=3$

$q=6$

Step-by-step explanation:

If $x=2$ , then $x-2=0$ .

Therefore:

$x^2-5x+q=0$

$2^2-5(2)+q=0$

$4-10+q=0$

$-6+q=0$

$q=6$

This means that the other root is $x=3$ since $(x-2)(x-3)=x^2-5x+6$
