Question

3.
a+b=5 and a2-b2=5 find quadratic equations

Answer 1

Answer:

a=3

b=2

Step-by-step explanation:

a2-b2=(a+b)(a-b)

we know the value of LHS and a+b

5=5×(a-b)

so a-b=1

we know a+b=5

so 2a=6

therefore a=3 b=2

Answer 2

Answer:

a+b=5

(a-b)(a+b)=5

=a-b=5/5=1

adding the both equation

a+b+a-b=5+1

2a=6

a=3

b=5-a=5-3=2
