Question

factorise following (1 to 9) polynomial ax +a^2x + any +by - (ax+by)^2​

Answer 1

Step-by-step explanation:

i)x−1−(x−1)

2

+ax−a

=(x−1)−(x−1)

2

+a(x−1)

=(x−1)[1−(x−1)+a ]

=(x−1)(1−x+1+a)

=(x−1)(2−x+a)

(ii)ax+a

2

x+aby+by−(ax+by)

2

=(ax+by)+(a

2

x+aby)−(ax+by)

2

=(ax+by)+a(ax+by)−(ax+by)

2

=(ax+by)[1+a−(ax+by)]

=(ax+by)(1+a−ax−by)
