I need help please!

Answer 1

Answer:

The correct option is

The polynomial is prime.

Step-by-step explanation:

we have to select the true statement for the equation

$x^2+8x-6$

As, we know if $b^2-4ac$ is a positive perfect square integer, then the trinomial can be factored over the rational numbers. Otherwise, we cannot factor $ax^2 + bx + c$ over the rational numbers,

so the trinomial is considered to be prime.

Equation: $x^2+8x-6$

a=1, b=8 and c=-6

$b^2-4ac=8^2-4(1)(-6)=64+24=88$

which is not a perfect square integer.

Hence, the above trinomial can not be factored into lowe degree.

⇒ Given polynomial is prime.

hence, option 4 is correct.
