2 Help 3x² +8x+ 5-14 Which constant would you add - 1

Answers

Answer 1
Answer:

ANSWER

The correct answer is D

EXPLANATION

The given quadratic expression is

3 {x}^(2) + 8x = - 1

Divide through by 3

{x}^(2) + (8)/(3) x = - (1)/(3)

We now add the square of half the coefficient of x because the coefficient of the quadratic term is now unity.

The constant we would add is

{( (4)/(3) )}^(2) = (16)/(9)

The correct answer is D
Answer 2
Answer:

Answer: Option D.

Step-by-step explanation:

Given the quadratic equation 3x^2+8x=-1, you can observe that the leading coefficient is not 1, then you have to divide both sides of the equation by 3:

(3x^2+8x)/(3)=(-1)/(3)\n\nx^2+(8)/(3)x=(-1)/(3)

Now, you can observe that the coefficient of the x-term is (3)/(8), so you must divide it by 2 and square it. Then you get:

(((8)/(3))/((2)/(1)))^2=(16)/(9)

Therefore, you must add (16)/(9) to both sides of the equation.

5/7-2/5=

Answers

If you would like to calculate 5/7 - 2/5, you can do this using the following steps:

5/7 - 2/5 = 25/35 - 14/35 = (25 - 14) / 35 = 11/35

The correct result would be 11/35.
the answer is 11/35
