Question

निम्नलिखित के गुणनखण्ड कीजिए

(i) a(a – 5) + 9 (5 – a)

(ii) (z-2) -3 (z-2)

(iii) 17 (a +3) +17 (3 – a)

Answer 1

(i)

a(a – 5) + 9 (5 – a)

= a(a – b) + 9(5 – a)

= (a – 5) (a – 9)

(ii)

(z – 2)² – 3(z – 2)

= (z – 2) (z – 2 – 3)

= (z – 2) (z – 5)

(iii)

17 (a + 3) + 17 (3 – a)

= 17 (a + 3) – 17 (a – 3)

= 17 (a + 3 – a + 3)

= 17 × 6 = 102
