Question

If a- b = 1 and ab =12, then a²+b² =​

Answer 1

Answer:

GIVEN

a-b=1

squaring on both the sides

(a-b)²=a²+b²-2ab

so putting the given values we get

(1)²=a²+b²- 2×12

a²+b²=24+1

a²+b²=25

if you understand pls mark me brainliest

Answer 2

a=4

b = 3

therefore a^2-b^3=( a-b)^2ab

=(4-3)^2 +2*4*3

=1+24

= 25
