Step-1

Title: Determine the value of an expression by substituting the values

Grade: 6-b Lesson: S4-L4

Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Determine the value of an expression by substituting the values a = 1,b = -2,c = 3	\$ (a+b+c)^2 \$
2	Now substitute "a,b,c" values in the expression	\$ (1 + (-2) + 3)^2 \$
3	After simplification we get	\$ (1 - 2 + 3)^2 \$
4	After simplification we get	\$ (4 - 2)^2 \$
5	After simplification we get	\$ 2^2 \$
6	After simplification we get	\$ 4 \$
7	Answer	C = \$ 4 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the values
a = 1,b = -2,c = 3

\$ (a+b+c)^2 \$

Now substitute "a,b,c" values in the expression

\$ (1 + (-2) + 3)^2 \$

After simplification we get

\$ (1 - 2 + 3)^2 \$

After simplification we get

\$ (4 - 2)^2 \$

After simplification we get

\$ 2^2 \$

After simplification we get

\$ 4 \$

Answer

C = \$ 4 \$
