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
