Equation = x2-2x-3=0

For equation ax2+bx+c=0

Roots are given as =2a−b±b2−4ac

Now let us compare ax2+bx+c=0 with x2−2x+3=0 to find the values of a,b,c

After it we can directly put a,b,c into the formula to find the roots

By comparing a=1,b=−2,c=3

So roots =2×1−(−2)±(−2)2−4(1)(3)

               =22±4−12

               =22±−8

               =1±i2

Hence the roots of the equation x2−2x+3=0 are imaginary 

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

the answer is d
