The roots of the quadratic equation ax2 + bx + c = 0, a ≠0 are given by the following formula: In this formula, the term b2–4ac is called the discriminant. If b2–4ac = 0, then the equation has a single (repeated) root. If b2–4ac > 0, the equation has two real roots.

a) here roots are m=4 and n=9

so m+n= 4+9= 13/1 = -b/a

mn= 4×9 = 36/1=c/a

so, a=1 b= -13 c= 36

therefore; ax2 +bx+c=0

x2+-13x+36=0


loljanna42: oooh i got right for the a but can you help me with the b one? i dk how to do it :( thanks
