Find the zeros of each of the following quadratic polynomials and verify therelationship between the zeros and their coefficients:(i) f(x) = x2 - 2x -- 8 INCERT (ii) g(s) = 4s?4st 1INCERTI(iii) h(t) = 12 - 15INCERTI (iv) f(x) = 6x2 - 3 - 7xINCERT)(v) P(x) = x2 + 2V2 x - 6(vi) g(x) = 13x² + 10x + 713HIN |

Answer» Step-by-step explanation: = x² -4X +2x -8 = x(x - 4)+2(x -4) =(x-4) (x +2) x -4 =0 x + 2 = 0 x= 4 and x= -2 soz = - (coefficient of x) (coefficient of x²) soz = 4+(-2)=2 -(-2/1) -b/a poz = 4x(-2)= -8 c/a 2. 4s² - - 4s+1 4s²-2s-2s+1 2s(2s-1)-1(2s-1) 2s-1=0 2s-1=0 s=½ s=½ 5. t² -15 (t-√15)² (t+√15) t=√15 t= √15 -√15 |
