Question

m, n are zeroes of ax2
– 12x + c. Find the value of a and c if m + n = m n = 3

Answer 1

Answer:

a=4,c=12

Step-by-step explanation:

Given,

m and m are the roots oc the quadratic equation:

ax²-12x+c=0

Also given,

m+n=m×n=3

Now,

• m+n=-(-12/a)
• 3=12/a
• a=4

Similarly,

• m×n=c/a
• 3=c/4
• c=12

Answer 2

Answer:

Answer:

a=4,c=12

Step-by-step explanation:

Given,

m and m are the roots oc the quadratic equation:

ax²-12x+c=0

Also given,

m+n=m×n=3

Now,

m+n=-(-12/a)

3=12/a

a=4

Similarly,

m×n=c/a

3=c/4

c=12
