Question

If one of the quadratic polynomial x2-5x-6; is 6 then the other zero is

Answer 1

Answer:

∴ the another zero of the quadratic equation is -1

Step-by-step explanation:

a =1 and b = - 5 and c = -6

-b ±√b² - 4ac ÷2a

= 5±√25 - [(4)(1)(-6)] / 2

= 5 ±√25+24 /2

= 5 ±√49 /2

= 5+7/2     ;      5-7/2

= 6  ; -1
