1)

(x + 3) (x - 5)

(x.x - 5.x + 3.x - 3.5)

x² - 5x + 3x - 15

x² - 2x - 15.

.............................................................................

2)

(x - 2)(x - 4)

(x.x - x.4 + 2.x - 2.4)

x² - 4x + 2x - 8

x² - 2x - 8

.............................................................

Binomio al cuadrado.

(a - b)² = a² + 2ab - b²

.............................................................

(3x² - 5)² = 3²(x²)² + 2(3x²)(5) - 5²

= 9x⁴ + 30x² - 25

Macorina 1) (X+3) (X-5) = x² - 5x + 3x - 15 = x² - 2x - 15

2) (X-2) (X-4) = x² - 4x - 2x + 8 = x² - 6x + 8

3) (3x² -5)² = $9x^{4} - 30x^{2} + 25$
