The expand each binomial. (x - 2)⁵ is:
x⁴ - 8x³ + 24x² - 32x + 16
A polynomial is a set of numbers and letters that make up an expression that has a meaning, the letters are variables and the numbers are coefficients or independent terms.
Depending on the number of terms it can be :
We solve first by perfect square trinomial, then we apply the distributive property.
(x - 2)⁴ = (x- 2)²(x - 2)²
(x - 2)⁴ = (x² - 4x + 4)(x² - 4x + 4)
(x - 2)⁴ = (x⁴ - 4x³ + 4x²) + (-4x³ + 16x² - 16x) + (4x² - 16x + 16)
(x - 2)⁴ = x⁴ - 4x³ + 4x² -4x³ + 16x² - 16x + 4x² - 16x + 16
(x - 2)⁴ = x⁴ - 8x³ + 24x² - 32x + 16
