Question

If a minus b is equals to 4 and a + b is equals to 6 find a square + b square and ab

Answer 1

Answer:

36

Step-by-step explanation:

A-B=4 ---------(equation 1)

A+B=6 ---------(equation 2)

Adding Equation (1) and (2)

A-B=4

+A+B=6

________

2A. =10

A= 10/2

A= 5

Put A=5 in Equation (1)

A - B = 4

5 - B = 4

-B = 4 - 5

- B = - 1

B = 1

A= 5 and B= 1

A^2 + B^ 2× AB = 5^2 + 1^2 +(5×2)

= 25 + 1+(10)

= 26+10

1. = 36
