The answers are - 3 and 5.
Answer:
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- 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 ,
<u>Given </u><u>equation</u><u> </u><u>:</u><u>-</u>
Step 1: <u>Find</u><u> out</u><u> the</u><u> </u><u>factors</u><u> </u><u>of </u><u>1</u><u>2</u><u> </u><u>:</u><u>-</u><u> </u>
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 :<u> Breaking</u><u> the</u><u> </u><u>middle</u><u> term</u><u> </u><u>:</u><u>-</u><u> </u>
Step 3: <u>Take </u><u>out </u><u>common</u><u> </u><u>from </u><u>terms </u><u>:</u><u>-</u>
Step 4 : <u>Equate </u><u>them </u><u>with </u><u>0</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence </u><u>the</u><u> </u><u>correct</u><u> </u><u>options </u><u>are </u><u>C </u><u>and </u><u>D </u><u>.</u>

Answer:
Hey Dude ok so it's g = 7 Have a nice day!
Step-by-step explanation:Simplifying
-2 = g + -9
Reorder the terms:
-2 = -9 + g
Solving
-2 = -9 + g
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Add '-1g' to each side of the equation.
-2 + -1g = -9 + g + -1g
Combine like terms: g + -1g = 0
-2 + -1g = -9 + 0
-2 + -1g = -9
Add '2' to each side of the equation.
-2 + 2 + -1g = -9 + 2
Combine like terms: -2 + 2 = 0
0 + -1g = -9 + 2
-1g = -9 + 2
Combine like terms: -9 + 2 = -7
-1g = -7
Divide each side by '-1'.
g = 7
Simplifying
g = 7
