Answer 1

Step-by-step explanation:

1. x² - 2x --8

= 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
