Question

find zeros of polynomial 4x^2-9

Answer 1

The answer is given below :

Now,

4x^2 - 9

= (2x)^2 - 3^2

= (2x + 3)(2x - 3)

So, the zeroes of the given polynomial are

-3/2 and 3/2.

Identify Rule :

a^2 - b^2

= (a + b)(a - b).

Thank you for your question.

Answer 2

HEY!!

_________________________

✔To find zeros of 4 x 2 - 9  we equate it to zero and get

✔4 x 2 - 9  = 0

✔4 x 2 = 9 

✔x 2 = 94

✔x = ± root 9/4  = ±3/2

Therefore,

▶▶Zeroes :  x  = 3/2 and  - 3/2
