The quadratic graph whose sum of zeroes is 0 and that of its product is -1 is given by

(a) y = x2

– x (b) y

Question

The quadratic graph whose sum of zeroes is 0 and that of its product is -1 is given by   (a) y = x2  – x (b) y = x2 + x (c) y = x2  – 1 (d) y = x2 + 1​

Step-by-step explanation:    given  : that  : sum  : of  : zeroes  : is  : 0      : and  : product  : is  :  - 1     we     know     that     sum     of     zero         is     -b/    a     and     product     of     the     zeroes     is     c/    a            frac{0}{1} =   frac{ - b}{a}      here  : we  : got  : b  :  = 0  : and  : a = 1  :        now         let's     find     c         frac{ - 1}{1}  =   frac{c}{a}     here  : from  : the  : sum  : of  : the  : equation  :     we  : got  : that  : a  :  = 1  : and  : c  :  =  - 1           therefore         we     got     all     the     values          quadratic  : equation  : is      {ax}^{2}  + bx + c = 0    1 {x}^{2}  + 0x + ( - 1) = 0    therefore  : we  : got      {x}^{2}  + 0x - 1 = 0             Hope     it     helps
