Question

if a+b=6 and ab=5 find a and b​

Answer 1

Answer:

a = 1,5.

b = 1,5.

Step-by-step explanation:

a+b = 6

so, b = 6-a

now, ab=5

so, 6a-a^2 = 5

a^2 - 6a + 5 = 0

a^2 - a - 5a + 5 = 0

a(a-1) - 5(a-1) = 0

(a-1) (a-5)=0

So, a = 1,5.

Thus, b = 1,5.

Answer 2

Answer:

a+b=6

ab=5

b=5/a

Substitute the value

5/a+a/1=6

a^2+5-6a=0

a^2-5a-a+5=0

x=5

y=1
