Question

find the zeros and verify the relationship between its zeros and the coefficient. x square + X - 2​

Answer 1

Answer:

x2+x-2

x2+2x-x-2

x(x+2)-1(x+2)

(x-1)(x+2)

x -1 = 0 and x+2=0

x = 1 and x = -2

sum of twp ratio = -b/a

1+(-2) = -1/1

-1= -1

product of two ratioe = c/ a

1(-2) = -2/1

-2 = -2
