Question

zeroes of 7x^2-63 are ​

Answer 1

Answer:

There are two zeros in the polynomial.

7x^2-63

7( x^2- 9)

7( (x)^2- (3)^2)

7( (x+ 3)(x-3))

zero of polynomial is 3 and (-3)

checking

7(3)^3-63

7(9)-63

63-63

0

7(-3)^2-63

7(9)-63

63-63

0

Additional information

zeros of polynomial is the number through which the whole polynomial become zero .

Number of zeros can be found by the degree of polynomial.
