1. If x = 2, calculate the value of: x cubed + x squared
2 answers:
1. 2^2=4
Sqrt(2) ≈1.4
4+1.4=5.4
2. -2^2 = -4
Sqrt(-2) = -1.4 i -> 1
3. 3x + 2 = 14
3x=12
X= 4
Answer:
- The answer is 12
- The answer is -4
- The value of x is 4
Step-by-step explanation:
For both Q1 and Q2, you have to substitute the value of x into the expressions :
Q1.
x³ + x²,
Let x = 2,
2³ + 2² = 8 + 4
= 12
Q2.
x³ + x²,
Let x = -2,
(-2)³ + (-2)² = -8 + 4
= -4
For Q3, you have to move all the related variable to one side and unrelated value to the other side :
5x + 2 = 2x + 14
5x + 2 - 2x = 14
3x = 14 - 2
3x = 12
x = 4
