Check all of the polynomial functions that have 2 as a root. h(m) = 8 – m3 f(g) = g3 – 2g2 + g f(a) = a3 – 4a2 + a + 6 f(x) = x3 – x2 – 4

On ed2020, the correct answers are A, C and D

Step-by-step explanation:

Option A , C and D are correct

Step-by-step explanation:

If x = a is the root of the polynomial p(x)

then;

p(a) = 0

Given that:

The polynomial functions that have 2 as a root.

Option A:

if 2 is the root of the polynomial h(m) then;

⇒h(m) is the polynomial functions that have 2 as a root.

Option B.

Put g = 2

then;

⇒f(g) is the polynomial functions that does not have 2 as a root.

Option C:

Put a = 2

then;

⇒f(a) is the polynomial functions that have 2 as a root.

Option D:

Put x= 2

then;

⇒f(x) is the polynomial functions that have 2 as a root.

step-by-step explanation:

y=mx+b

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
