Pre-Algebra Examples

$x^{4} + x - x^{2}$ , $x^{3} - 4 x^{2} + 5$ , $7 x^{2} - 4 x + 6$

Step 1

Subtract $4 x$ from $x$ .

$x^{4} - x^{2} + x^{3} - 4 x^{2} + 5 + 7 x^{2} - 3 x + 6$

Step 2

Subtract $4 x^{2}$ from $- x^{2}$ .

$x^{4} + x^{3} - 5 x^{2} + 5 + 7 x^{2} - 3 x + 6$

Step 3

Add $- 5 x^{2}$ and $7 x^{2}$ .

$x^{4} + x^{3} + 2 x^{2} + 5 - 3 x + 6$

Step 4

Add $5$ and $6$ .

$x^{4} + x^{3} + 2 x^{2} - 3 x + 11$

Step 5

Since there are no common prime factors, the GCF is $1$ .
