Question

If a = 2, b = 3 and c = 4, what is the numerical value of the expression (b-c)^2 + a(b+c)?

Answer 1

Answer:

• 15

Step-by-step explanation:

We know that:

• Given expression: $(b-c)^2 + a(b+c)$
• a = 2
• b = 3
• c = 4

Solution:

• $(b-c)^2 + a(b+c)$
• => $(3-4)^2 + 2(3+4)$
• => $(-1)^2 + 2(7)$
• => $[-1(-1)] + 2(7)$
• => $1 + 14$
• => $15$

Answer 2

Answer:

15

Step-by-step explanation:

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

(-1)^2 + 2(7)

1 + 14

15
