Question

if the sum of two given numbers a and b is 7 and product is 12 a²- ab+b² find the value​

Answer 1

The value of a = 4

The value of b = 3

By multiplying 4 and 3 = 13

adding 4 and 3 = 7

Answer 2

Answer:

13

Step-by-step explanation:

(a+b)^2 = a^2+b^2 + 2ab

(7)^2 = a^2+b^2 + 2 x 12

49 =a^2+b^2 + 24

a^2+b^2 = 49 - 24

a^2+b^2 = 25

a^2 - ab + b^2

a^2+b^2 - ab

25 - 12

13
