Question

Que es mas grande 15(x+1/2)(x-1)

Answer 1

Respuesta:

15(x+1/2)(x-1)

(15x+15/2)(x-1)

$15x^{2} +15x\left(-1\right)+\frac{15}{2}x+\frac{15}{2}\left(-1\right)\\\\15x^{2} -15x+\frac{15}{2}x-\frac{15}{2}\\\\15x^2-15x+\frac{15x-15}{2}\\\\\frac{30x^2-15x-15}{2}\\\\\frac{30x^2}{2}-\frac{15x}{2}-\frac{15}{2}\\\\15x^2-\frac{15x}{2}-\frac{15}{2}$
