In which situation would you most likely factor out -1 from a trinomial? a) when the coefficient of x is negative b) when the coefficient of x^2 is negative c) when the constant term is negative

B) when the coefficient of x^2 is negative

  when the coefficient of x^2 is negative

Step-by-step explanation:

Suppose if we have a trinomial  x^2 - 5x+6

We can factor this trinomial by finding two factors whole product is +6 and add upto -5

Suppose we have a trinomial -x^2 +5x-6

Here factoring is not possible directly

so we need to factor out  negative from x^2

To factor any trinomial x^2 should be positive

So we factor out -1 when the coefficient of x^2 is negative

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
