Question

write a quadratic function in standard form having zeros of 2 and -11

Answer 1

sum of the zeroes = 2+(-11)
                               =-9
product of zeroes =2× (-11)
                               =-22
quadratic equation= x²- x(sum of zeroes) + (product of zeroes)
                                 =x²-(-9)x+(-22)
                  equation⇒x²+9x-22
