Answer: Step 1: Divide both sides by -2

Step 2: Simplify to

Step 3: Simplify to 2

3y + 5 = 2

Step 4: Subtract 5 from both sides

3y = 2 - 5

Step 5: Simplify 2 - 5 to −3

3y = -3

Step 6: Divide both sides by 3

Step 7: Cancel 3

y = -1

Done! :) your answer is y = -1 3

Step 2: Simplify to

Step 3: Simplify to 2

3y + 5 = 2

Step 4: Subtract 5 from both sides

3y = 2 - 5

Step 5: Simplify 2 - 5 to −3

3y = -3

Step 6: Divide both sides by 3

Step 7: Cancel 3

y = -1

Done! :) your answer is y = -1 3

Find the value or values of y in the quadratic equation y2 + 4y + 4 = 7. A. y = −2 + √ 7 , y = −2 − √ 7 B. y = 2, y = 7 C. y = −2√ 7 , y = 2√ 7 D. y = 2 + 2√ 7 , y = 2 − 2√ 7

Answer:

Option A

The values of y are: or .

Step-by-step explanation:

Subtract 7 from both the sides:

On Simplify:

Solve with the quadratic formula:

For a quadratic equation of the form the solutions are:

For a=1, b=4 and c=-3 we have,

=

on solving we get, =

therefore, the values of y are:

or

A) y = -2 + rt7, y = -2 - rt7
