Factor 4x^2-4x-8 Please help

Mathematics
2 answers:
gavmur [86]3 years ago

Answer:

4x² - 4x - 8 can be factored into 4(x - 2)(x + 1)

Step-by-step explanation:

First, we can factor out 4, as all terms are divisible by that:

4x² - 4x - 8

= 4(x² - x - 2)

Now we need to find two numbers that are are factors of -2, but add up to -1.  -2 and 1 meet that condition, so let's split the middle term into those coefficients:

=4(x² + x - 2x - 2)

= 4( x(x + 1) - 2(x - 1) )

= 4(x - 2)(x + 1)

Answer:

4(x+1)x(x-2)

Step-by-step explanation:

Step 1: factor it

4(x^2-x-2)

Step 2: re write the expression and make -x as a difference

4(x^2+x-2x-2)

Step 3: factor out x from the expression

4(x *(1+1)-2(x+1))

Step 4: factor out x+1 from the expression

4(x+1) x (x-2)

Das it hope you have a good day lol

Which of the following describes an equilateral triangle? Circle all that apply.
alexdok [17]

Answer:

A, B, and C

Step-by-step explanation:

The equilateral triangle refers to its equivalent sides and angles. So automatically, D would be ruled out.

Equilateral triangles have the same angles, so that would rule out E, because one 90° angle means it is a right triangle. Based on the explanation above, the answer would be A and B. C can be confusing but here's the explanation:

A triangle's sum of interior angles is 180°,  so if a triangle has three sides, it also has three angles. So if you divide 180 into 3 equal parts, you get 60° each. So technically C is correct.

Answers: A, B, and C.

Susan was thinking of a number that when she multiplies it by two and then
Gnesinka [82]

Answer:

-4

Step-by-step explanation:

Let the number be x

If she multiplies the number by 2, it will become 2x

If divided by 4, it will be 2x/4, if she multiplies the result by itself, we will have:

2x/4(2x/4) = 4x/16

If she subtract the original number from 6 and divide by 10, we will have;

x-6/10

Equating both expressions

4x/16 = x-6/10

Cross multiply

4x(10)= 16(x-6)

40x =16x-96

40x-16x = -96

24x = -96

x = -96/24

x = -4

Hence the number is -4
