Write a quartic trinomial with a leading coefficient of 2 using standard form
lions [1.4K]
Quartic => polynolial degree 4, i.e. the highest exponent of the variable is 4

trinomial=> three terms

leading coefficient = the coefficient in front of the term with the highest exponent.

standard form=> ax^4 + bx^3 + c^2 + dx + e

Solution:

2x^4 + x^3 + 0x^2 + 0x + 30

which is equal to 2x^4 + x^3 + 30: this is a quartic trinomial with leading coefficient 2, written in standard form.

Determine two numbers that have a product of 40 but have a sum of 13.
Paha777 [63]

Answer:

The two numbers are 8 and 5.

Step-by-step explanation:

Let consider x and y to be these two numbers.

So;

(x) * (y) = 40 ---- (1)

x + y     = 13 ----- (2)

From (2), let x =  13 - y

Then;

(13 - y) * y = 40

13y - y² = 40

13y - y² - 40 = 0

-y² + 13y - 40 = 0

Multiply through by (-)

y² - 13y + 40 = 0

By factorization;

(y - 8) (y - 5) = 0

y = 8 or  y = 5

CHECK:

8 * 5 = 40

8 + 5 = 13

Therefore, the two numbers are 8 and 5.
