Answer:
x = 4
Step-by-step explanation:
(5x2 - 2x + 1) = (x - 1)
Simplify by multiplying 5 and 2.
(10 - 2x + 1) = (x - 1)
Combine like terms. Remove parentheses.
11 - 2x = x - 1
Cancel out - 2x to get the variable on one side.
- 2x + 2x = 0 x + 2x = 3x
11 = 3x - 1
Do the same with the 1.
12 = 3x
Divide.
x = 4
