Factor out the largest term possible

Question

12x⁵ -4x²+16x³=

Answer 1

12x⁵ = 2 • 2 • 3 • x • x• x • x • x

-4x² = -1 • 2 • 2 • x • x

16x³ = 2 • 2 • 2 • 2 • x • x • x

What do they all have in common? 2 • 2 • x • x = 4x²

Combine what's left and put them in descending exponent order.

12x⁵ = 4x²(3x³)

-4x² = 4x²(-1)

16x³ = 4x²(4x)

4x²(3x³ + 4x - 1)

Answer 2

(4x^2)( 3x^3-1+4x)
