Question

Find the zeroes of the polynomial p(x) = 15x + 16x +4. Verity the relationship between the zeros and the coefficient​

Answer 1

ANSWER:-

p(x) = 15x^2 + 16x + 4 =0

15x^2 + 10x + 6x + 4 =0

5x (3x+2) + 2(3x+2) =0

(3x+2) (5x+2) =0

3x+2=0. 5x+2 =0

x = -2/3. [¥] x = -2/5 [£]

¥ + £ =-b/a

-2/3 + -2/5 = -16/15

-16/15 = -16/15

¥ × £ = c/a

-2/3 × -2/5 = 4/15

4/15 = 4/15

Hence. verified.....
