Question

Find the zeros of the polynomial x cube -15x square

Answer 1

$\huge{\underline{\underline{\mathbb{\blue{Answer}}}}}$

$\longrightarrow$${x}^{2} (x - 15) = 0$

$\longrightarrow$$x = 0 \\ x = 15$

$\huge{\underline{\underline{\mathcal{\blue{ThAnKs}}}}}$

Answer 2

x³- 15x² = 0

x²(x-15) = 0

x-15 = 0/ x²

x-15 = 0

x = 15
