Question

If a+ b is 9and a into b is 20 then solve a square + b square

Answer 1

Answer:

a=4, 5

B=5, 4

Step-by-step explanation:

a+b=9

b=9-a

a. B=20 (1)

put the value of B in (1)

then, a. (9-a)=20

9a-a^2=20

multiply by -1

a^2-9a+20=0

a^2-5a-4a+20=0

a(a-5) -4(a-5) =0

a-4=0,a-5=0

a=4,a=5

b=5,b=4

=a^2+b^2

=(4)^2+(5)^2

=16+25=41
