Answer:
9x² - 8x - 6 = 0
Step-by-step explanation:
11 - 4x = (3x - 2)² + 1
FOIL the (3x - 2)².
(3x - 2)² = (3x - 2)(3x - 2) = 9x² - 12x + 4
Rewrite the Equation.
11 - 4x = 9x² - 12x + 4 + 1
Move all to one side and combine like terms.
9x² - 8x - 6 = 0
Answer:
B
Step-by-step explanation:
Given
11 - 4x = (3x - 2)² + 1 ← expand the squared factor using FOIL
11 - 4x = 9x² - 12x + 4 + 1, that is
11 - 4x = 9x² - 12x + 5 ( add 4x to both sides )
11 = 9x² - 8x + 5 ( subtract 11 from both sides )
0 = 9x² - 8x - 6 or
9x² - 8x - 6 = 0 → B
