Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x+2)=2(x+5)
(3)(x)+(3)(2)=(2)(x)+(2)(5)(Distribute)
3x+6=2x+10
Step 2: Subtract 2x from both sides.
3x+6−2x=2x+10−2x
x+6=10
Step 3: Subtract 6 from both sides.
x+6−6=10−6
x=4
Answer:
4/3
Step-by-step explanation:
Answer:
x = - 1, x = 1, x = 2
Step-by-step explanation:
The coefficients of the polynomial sum to zero, that is
- 1 + 2 + 1 - 2 = 0
This indicates that x = 1 is a zero
let x = - 1, then
- (- 1)³ + 2(- 1)² + (- 1) - 2 = 1 + 2 - 1 - 2 = 0
Thus x = - 1 is a zero
let x = 2
- (2)³ + 2(2)² + 2 - 2 = - 8 + 8 + 2 - 2 = 0
Thus x = 2 is a zero
The 3 zeros are x = - 1, x = 1, x = 2
