Question

14. Find the zero of polynomial in
I) p (x) =5x-3
II) p(x) = cx + d, c#0, c, d
are real numbers.​

Answer 1

Answer:

1) p(x) =5x-3

= 5x-3=0

5x=3

x=3/5

2) p(x)=cx+d

cx+d =0

cx=-d

x=-d/c Answer.

Answer 2

i) p(x) = 5x-3

p(x) = 5x-3

p(x) = 0

5x-3 = 0

5x = 3

x = 3/5

ii) p(x) = cx + d

p(x) = cx + d

p(x) = 0

cx + d = 0

1x + 2 = 0

x = -2
