Answer:
x(x - 4) = 12
x2 - 4x = 12
x2 - 4x - 12 = 0
(x - 6)(x + 2) = 0
x - 6 = 0
x = 6
If the length is 6, the width must be 2.
Step-by-step explanation:
9 x 8= 72, so the answer would be:
72
Answer:
"Take the square root of both sides of the equation"
A is correct
Step-by-step explanation:
We are given quadratic equation
We need to solve for x. We have to isolate x here.
Here square on x. So, first we get rid of square.
Taking square root both sides to get rid of square.
For example:
a2=25
sqare a2 = +- sqare 25
x2=9/16 to solve for x
sqare x2 +- sqre 9725
x=+- 3/5
Hence, "Take the square root of both sides of the equation"
