Answer:
The greatest common factor of 4 is 4
Step-by-step explanation:
1*4
2*2
4 is the biggest number that goes into 4
x2(x + 9) – 5(x + 9)
x(x2 + 5) – 9(x2 + 5)
x(x2 – 5) – 9(x2 – 5)
The answer choice which shows a way to determine the factors by grouping is; x(x² + 5)–9(x² + 5).
According to the task content, the factors of the expression are to be determined by grouping.
On this note, one way to group the factors would be;
x³ + 5x - 9x² -45
Upon factorisation;
x(x² + 5) – 9(x² + 5).
