Which expression is equivalent to -1/4( -1/2x - 3/4) -1/2 ( 3/4x + 1/8)

solniwko [45]

Answer:

Step-by-step explanation:

$\frac{-1}{4}(\frac{-1}{2}x-\frac{3}{4})-\frac{1}{2}(\frac{3}{4}x+\frac{1}{8})\\\\=\frac{-1}{4}*\frac{-1}{2}x-\frac{-1}{4}*\frac{3}{4}-\frac{1}{2}*\frac{3}{4}x-\frac{1}{2}*\frac{1}{8}\\\\=\frac{1}{8}x+\frac{3}{16}-\frac{3}{8}x-\frac{1}{16}\\\\=\frac{1}{8}x-\frac{3}{8}x+\frac{3}{16}-\frac{1}{16}\\\\=\frac{(1-3)x}{8}+\frac{3-1}{16}\\\\=\frac{-2}{8}x+\frac{2}{16}\\\\=\frac{-1}{4}x+\frac{1}{4}$

Which of the binomials below is a factor of this trinomial? x2 + 6x + 8

navik [9.2K]

Answer:

(x+4)(x+2)

Step-by-step explanation:

Distributive property of 2 binomials:

First, outer, inner, last

(a+b)(c+d) = ac+ad+bc +bd

Factor x^2 into x*x

Factor 8 into 2*2*2

Find what two numbers add up to 6 and multiply to get 8

1 and 8 do not work because they add up to 9. 2 and 4 work because they add up to 6.

Check: (x+4)(x+2)

First: x*x = x^2

Outer: 2*x

Inner: 4*x

Last: 2*4 = 8

Add together: x^2+2x+4x+8 = x^2+6x+8
