Question

Realice los siguientes productos: a. 5 (x + 2) = b. (x2 + 3x – 5) (-4) = c. -1(3x – 4)

Answer 1

5(x+2)

=(5)(x+2)

=(5)(x)+(5)(2)

=5x+10

(x2+3x−5)(−4)

=(x2+3x+−5)(−4)

=(x2)(−4)+(3x)(−4)+(−5)(−4)

=−4x2−12x+20

−1(3x−4)

=(−1)(3x+−4)

=(−1)(3x)+(−1)(−4)

=−3x+4

$\boxed{espero// que// te// sirva }$

Answer 2

Explicación paso a paso:

a. 5 (x + 2) = 5x+10

b. (x² + 3x – 5) (-4) = -4x²-12x+20

c. -1(3x – 4)= -3x+4
