Mathematics
1 answer:
Tems11 [23]3 years ago
7 0

Answer:

4x^2 + 8x + 4

4(x^2 + 2x + 1) - remove GCF of 4

4(x + 1)(x + 1) - factor

4(x + 1)^2 - collect like terms

Step-by-step explanation:

Then also expand it out by distributing:

21x^3 + 35x²

Form 1:

21x^3 + 35x² - unfactored

Form 2:

7x²(3x + 5) - factored with GCF of 7x² brought to the front

Update:

You could also multiply two binomials and make a quadratic.

Example:

(7x + 2)(3x + 5)

7x(3x + 5) + 2(3x + 5)

= 21x² + 35x + 6x + 10

= 21x² + 41x + 10

Helga [31]

Answer:

−x^2−11

Step-by-step explanation:

Distribute the Negative Sign:

=−3x−4+−1(x^2−3x+7)

=−3x+−4+−1x^2+−1(−3x)+(−1)(7)

=−3x+−4+−x^2+3x+−7

Combine Like Terms:

=−3x+−4+−x^2+3x+−7

=(−x^2)+(−3x+3x)+(−4+−7)

=−x^2+−11

7.75 in expanded form
Elina [12.6K]

Answer: 7+0.7+0.05

Since 7 is in the ones place it goes in front of the decimal. .7 is in the tenth place because it's behind the decimal. .05 is also behind the decimal so it's in the hundredths place.
