Question

Find the zero of the polynomial p(x) =cx-d

Answer 1

Answer:

p(x) = cx - d = 0

p(x) = cx = d

p(x) = x = d/c

The zero of the polynomial p(x) =cx-d is d/c.

To check:-

p(d/c) = c(d/c) - d = 0

p(d/c) = d - d = 0 ( c got cancelled )

p(d/c) = 0 = 0

LHS = RHS

So, the value of x is d/c.

Answer 2

The zero of the polynomial p(x) = cx - d is d/c

Given :

The polynomial p(x) = cx - d

To find :

The zero of the polynomial

Solution :

Step 1 of 2 :

Write down the given polynomial

The given polynomial is p(x) = cx - d

Step 2 of 2 :

Find zero of the polynomial

For Zero of the polynomial we have

p(x) = 0

⇒ cx - d = 0

⇒ cx = d

⇒ x = d/c

The zero of the polynomial p(x) = cx - d is d/c
