Question

7. Find the zeroes of the quadratic polynomial p (x) = 4x2 + 5V2 x-3 and verify the
es, find relationship between the zeroes and the coefficients of the polynomial.​

Answer 1

Step-by-step explanation:

We have,

4x2 – 3x-7

= 4x2 - 7x + 4x - 7

= x(4x - 7) + 1(4x - 7)

= (4x - 7)(x + 1)

So, the value of 4x? - 3x - 7 is zero when

4x 7 = 0 or x +1 = 0 =

7 i.e., when x = or x = -1 4

Therefore, the zeroes of 4x? 3x -7 are 7 4

and -1

Now, Sum of zeroes = 7 + (-1) = 3 =

4 4

-(-3) -b

4

a

Product of zeroes = = 7 4 x (-1) -7 с

- 4 a

Hence verified.
