To get from 7-10=2(-3+8) to 7-10=-6+16, you have to use the distributive property because of the parenthesis. the next step would be adding 10 to both sides in order to even the equation (adding because it cancels out the negative and makes 0), and the last step you have is adding 6 to both sides of the equation to balance it. in order to get 2, you have to divide 26 by 13 (26/13). hope this helps!
Move all terms to one side
4w^2 + 49 + 28w = 0
Rewrite 4w^2 + 49 + 28w in the form a^2 + 2ab + b^2, where a = 2w and b = 7
(2w)^2 + 2(2w)(7) + 7^2 = 0
Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
(2w + 7)^2 = 0
Take the square root of both sides
3w + 7 = 0
Subtract 7 from both sides
2w = -7
Divide both sides by 2
<u>w = -7/2</u>
Answer:
1/2
Step-by-step explanation:
divide both sides by 14 and reduce 7/14 =1/2
y=1/2
All the solutions are here except number 5.
