Question

factories a^4-27a^2+1​

Answer 1

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

((a4) - 33a2) + 1

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring a4-27a2+1

The first term is, a4 its coefficient is 1 .

The middle term is, -27a2 its coefficient is -27 .

The last term, "the constant", is +1

Step-1 : Multiply the coefficient of the first term by the constant 1 • 1 = 1

Step-2 : Find two factors of 1 whose sum equals the coefficient of the middle term, which is -27 .

-1 + -1 = -2

1 + 1 = 2

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

a4 - 27a2 + 1
