Quadratic in Form Polynomials

Question 1

Use substitution to write an equivalent quadratic equation.(3x + 2)2 + 7(3x + 2) – 8 = 0u² + 7u - 8 = 0, where u = (3x + 2)²u² + 7u - 8 = 0, where u = 3x + 2u² + 7u - 8 = 0, where u = 7(3x + 2)u² + u - 8 = 0

Revolt · Accepted Answer

B: u² + 7u - 8 = 0, where u = 3x + 2

Question 2

Which equation is equivalent tof(x) = 16x4 – 81 = 0?(4x² - 9)(4x² - 9) = 0(4x² + 9)(4x² - 9) = 0(4x - 9)(4x - 9) = 0(4x + 9)(4x - 9) = 0

Revolt · Accepted Answer

B: (4x² + 9)(4x² - 9) = 0
