Question

if a = - 1, b = 2 , c = 0 , find the value of 2 a² + 6 - 2 b + 4c

Answer 1

Answer:

4

Step-by-step explanation:

Plug in the values to the expression and solve:

2a² + 6 - 2 b + 4c

2(-1)² + 6 - 2(2) + 4(0)

Solve:

2(-1)² + 6 - 2(2) + 4(0)

2(1) + 6 - 2(2) + 4(0)

2 + 6 - 2(2) + 4(0)

2 + 6 - 4 + 4(0)

2 + 6 - 4

8 - 4

4

Your final answer would be 4.
