Question

Activity : Find the factors of the following polynomial
(1)x2 - 4x-5
= x2- 5x + 1x - 5
= x(.....) +1(.....)
= (....) (....)

(3) a2- 25
=(....) (.....)
(2) 2m2 - 5 m
= (....) (.....)​

Answer 1

Answer:

(1)x^2-4x-5

=(x^2-5x)+(x-5)

=x(x-5)+1(x-5)

=(x-5)(x+1)Ans

Answer 2

Answer:

2)2m^2-5m

=m(2m-5)

3)a^2-25

=a^2-5^2

=(a+5) (a-5)
