Answer 2

Answer:

ab = 5

Step-by-step explanation:

Given,

a² + b² = 6

a + b = 4

ab = ?

Now,

(a + b)² = a² + 2ab + b²

(a + b)² = a² + b² + 2(ab)

we know that

a + b = 4

a² + b² = 6

so,

4² = 6 + 2(ab)

16 = 6 + 2(ab)

16 - 6 = 2(ab)

10/2 = ab

ab = 5

Hope you understood it........All the best
