**Find the zeros of the following quadratic polynomials and verify the relationship between the zeros and the coefficients:**

**Question 1.**

**Solution:**

**Question 2.**

**Solution:**

x² – 2x – 8

Let f(x) = x² – 2x – 8

**Question 3.**

**Solution:**

**Question 4.**

**Solution:**

4x² – 4x – 3

**Question 5.**

**Solution:**

**Question 6.**

**Solution:**

**Question 7.**

**Solution:**

**Question 8.**

**Solution:**

**Question 9.**

**Solution:**

**Question 10.**

**Solution:**

**Question 11.**

**Solution:**

**Question 12.**

**Solution:**

**Question 13.**

**Solution:**

Zeros of a quadratic polynomial are 2, -6

**Question 14.**

**Solution:**

**Question 15.**

**Solution:**

Sum of zeros = 8

Product of zeros = 12

Quadratic equation will be x² – (Sum of zeros) x + Product of zeros = 0

=> x² – 8x + 12 = 0

=> x² – 6x – 2x + 12 = 0

=> x (x – 6) – 2 (x – 6) = 0

=> (x – 6) (x – 2) = 0

Either x – 6 = 0, then x = 6

or x – 2 = 0, then x = 2

Zeros are 6, 2

and quadratic polynomial is x² – 8x + 12

**Question 16.**

**Solution:**

Sum of zeros = 0

and product of zeros = -1

Quadratic equation will be

x² – (Sum of zeros) x + Product of zeros = 0

=> x² – 0x – 1 = 0

=> x² – 1= 0

(x + 1)(x – 1) = 0

Either x + 1 = 0, then x = -1 or x – 1 =0, then x = 1

Zeros are 1, -1

and quadratic polynomial is x² – 1

**Question 17.**

**Solution:**

Sum of zeros = \(\frac { 5 }{ 2 }\)

Product of zeros = 1

Quadratic equation will be

x² – (Sum of zeros) x + Product of zeros = 0

and quadratic polynomial is 2x² – 5x + 2

**Question 18.**

**Solution:**

**Question 19.**

**Solution:**

**Question 20.**

**Solution:**

**Question 21.**

**Solution:**

One zero of the given polynomial is \(\frac { 2 }{ 3 }\)

=> (x + 3) (x + 3) = 0

x = -3, -3

Hence, other zeros are -3, -3
