SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!!

Answer:

$y^2 + 8y + 16$

Step-by-step explanation:

$(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =$

The first set of parentheses is unnecessary, so it can just be removed.

$= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)$

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

$= 6y^2 + 2y + 5 - 5y^2 + 6y + 11$

Now you combine like terms.

$= 6y^2 - 5y^2 + 2y + 6y + 5 + 11$

$= y^2 + 8y + 16$

Select the two values of x that are roots of this equation.

makkiz [27]

Answer:

$\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}$

Step-by-step explanation:

Given :-

A quadratic equation is given to us.
The equation is 2x² + 7x +6=0

And we need to find out the roots of the given equation. We can use the middle term splitting method to find out the roots as ,

Given equation :-

$\implies 2x^2 + 7x +6=0$

Step 1: Find out the factors of 12 :-

We will choose the two factors such that their sum equals to the coefficient of x i.e. 7 .The factors are , 1×12 , 2×6 , 3×4 .

And 3 + 4 = 7. So we will break the middle term into 3x and 4x .

Step 2 : Breaking the middle term :-

$\implies 2x^2 + 3x+4x +6=0$

Step 3: Take out common from terms :-

$\implies x(2x + 3) +2(2x +3)=0$

$\implies ( x +2)(2x+3)=0$

Step 4 : Equate them with 0 :-

$\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}$

Hence the correct options are C and D .
