properly whole factorisation.​

Answer 1

Answer:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "a3" was replaced by "a^3".

STEP

:

Polynomial Roots Calculator :

2.1 Find roots (zeroes) of : F(a) = 8a3+8a-5

Polynomial Roots Calculator is a set of methods aimed at finding values of a for which F(a)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers a which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 8 and the Trailing Constant is -5.

The factor(s) are:

of the Leading Coefficient : 1,2 ,4 ,8

of the Trailing Constant : 1 ,5

I hope this helps you.
