Question

Verify that a = (b + c) * (a + b) + (a + c) for the
values of a, b and c
(i) a = 10, b = -2, c = 3
(ii) a = -8, b = 11, c = -3
​

Answer 1

Answer:

(i) a = 10, b = -2, c = 3

(b + c) * (a + b) + (a + c) = (-2 + 3) * (10 - 2) + (10 + 3)

                                     = (1)*(8)+(13)

                                     = 8 + 13 =21 (not equal to a)

(ii) a = -8, b = 11, c = -3

(b + c) * (a + b) + (a + c) = (11 - 3) * (-8 + 11) + (-8 - 3)

                                     = (8)*(3)+(-11)

                                     = 24-11 = 13 (not equal to a)

Thus, we can conclude a is not equal to (b + c) * (a + b) + (a + c).
