These simple ones kill me:
16y^2=49
Thanks
16y^2-49=0
(4y-7)(4y+7)=0
I see, thanks a lot.
S^2-5s-36=0
64x-121=0
To solve the equation 16y^2 = 49, you would need to isolate the variable y. Here's how you can do it step by step:
Step 1: Rewrite the equation
To start, write the equation in a way that makes it easier to work with. In this case, the equation is already in a simplified form, so no rearrangement is necessary.
16y^2 = 49
Step 2: Divide by the coefficient
Divide both sides of the equation by 16. This will give us:
(16y^2) / 16 = 49 / 16
Simplifying further:
y^2 = 49/16
Step 3: Take the square root
To get rid of the square on y^2, you need to take the square root of both sides of the equation:
√(y^2) = √(49/16)
Since y^2 is non-negative, we don't need to consider the negative square root.
y = √(49/16)
Step 4: Simplify the square root
Simplify the square root on the right-hand side:
y = √(49) / √(16)
The square root of 49 is 7, and the square root of 16 is 4:
y = 7/4
So the solution to the equation 16y^2 = 49 is y = 7/4.
