Consider the function, ? (?) = 20?² + 28? - 17
Determine both real roots of the quadratic equation asfollows:
i. Graphically and determine the intervals for bothroots to be used in iii & iv.
ii. Using the quadratic formula
iii. Using the bisection method until ?? is less than?? = 0.5%
iv. Using the false-position method until ?? is lessthan ?? = 0.5%
