1) Divide:
i) {25(x^5) - 15(x^4)} / 5(x^3).
ii) { 25(x^5) - 15(x^4)} /5.
iii){25(x^5) - 15(x^4)} /x.
iv) {25(x^5) - 15(x^4)}/ (x^2).
v) {25(x^5) - 15(x^4)} / {5(x^2) - 3x}.
2) factorise 6(x^2) + 35xy - 6(y^2).
3) factorise 2 - 32(x^2).
4) factorise i) 4(a^2) - 8a + 3.
ii) (a^2) - 1/ (b^2).​

Answer 1

Answer:

this question is wrong

Answer 2

y²-2y-15

y²-5y+3y-15

y(y-5)+3(y-5)

(y+3)(y-5)

factors are

(y+3)

and

(y-5)
