Question

5) form the quadratic equation if the root are - 3 and -11​

Answer 1

Answer:

if m and n are the roots of the quadratic equation ax²+bx+c=0

the sum is (m+n) and the product is (mn)

here, m= -3 and n= -11

• (m+n)=(-3)+(-11)= -14
• (mn)=(-3)×(-11)=33

So, the equation is,

ax²+(m+n)x+(mn)=0

ax²-14x+33=0

Hence, ax²-14x+33=0 is your answer
