Answer:
Q1: if x+y......
Step-by-step explanation:
Sum is 12 and product is 32
therefore, x+y = 8+4 = 12
and so xy = 8×4 = 32
therefore, x^2 + y^2
= 8^2 + 4^2
= 64 + 16
= 80

Answer:
(1.)Given
= x+y=12
& xy=32
formula x²+y²=(x+y)²- 2xy
= (12)²-2×(32)
=144-64
=80
cross check x²+y²= (8)²+(4)²= 80
x=8 and y=4
x+y = 8+4=12
xy =8×4=32
