Answer:
x2 + 10x +25 = (x+5)^2
Step-by-step explanation:
x^2 + 10x
To complete the square
Take the coefficient of x
10
Divide by 2
10/2 =5
Square it
5^2 =25
Add it
x2 + 10x +25
The coefficient of x divided by 2 is the factor we add to x inside the square
(x+5)^2
Answer:
y=6x
Step-by-step explanation:
The formula you use is y=mx+b you get 4x-3y=21 you add 3 to 3y and 21 then you cancel out the 3's 4x goes down and then you add 21+3 which equals 24 then you divide it all by 4 except y, you drop the y down and you should get y=6x
Hope you get it right
