Question

Factor out the GCF from the polynomial. 18x^6+ 81x^5 - 63x^2 +45

Answer 1

Answer:

The GCF is 9

Step-by-step explanation:

In the given polynomial $18x^6+ 81x^5 - 63x^2 +45$  lets represent each term  as its factors

$18x^6$ = $2 \times 3 \times 3 \times x \times x \times x \times x \times x \times x$

$81x^5$ = $3 \times 3 \times 3 \times 3 \times x \times x \times x \times x \times x$

$63x^2$ = $3 \times 3 \times 7 \times x \times x$

45 = $3 \times 3 \times 5$

The greatest common factors from each term  are  3 , 3

Thus the GCF =   $3 \times 3$ = 9
