The answer is incorrect.
The square of binomials is:
(a + b)² = a² + 2ab + b
In (5x³ + 3)², a = 5x³ and b = 3
Substitute it in the formula for the square of binomials:
(5x³ + 3)² = (5x³)² + 2 * 5x³ * 3 + 3² =
= 25x⁶ + 10x³ + 9
Louise’s answer is 25x⁶ + 9, which is incorrect.
Sixty one thousandths = .061
