Question

Factorise:
(a) x^4 -y^4
(b)27x^3 -8y^3
(c )64m^3 +125n^3

Answer 1

Answer:

Step-by-step explanation:

(a) x^4 -y^4

=  (x^2 + y^2)(x^2 - y^2)

(b)27x^3 -8y^3

=  (3x - 2y)(9x^2 + 6xy + 4y^2)

(c )64m^3 +125n^3

=  (4m + 5n)(16m^2 - 20mn + 25n^2)

Answer 2

Answer:

as_b² = ca-b) Ca²+al+102). 3 ... lax²+bx+c=0 form ... Factor each completely. 1) 4v2 - 9. 2) 9x2 - 4. 3) m2 - 1. 4) 962 - 16. 5) 12 – 16. 6) n ? ... 39) 8 - 27x3 ... 45) 64m +1 ... 80 ............??????
