Answer:
Step-by-step explanation:
steps are below
step 1
(2x+1)^2 - (x+3)^2 equation
step 2
4x^2+4x+1+(-x^2)+(-6x)+(-9) distribute
step 3
4x^2+4x+1+(-x^2)+(-6x)+(-9)
(4x^2+-x^2)+(4x+(-6x)+(1+(-9) combine the like terms
3x^2-2x-8
Answer: isolate the exponent term on one side of the equation, and then apply the appropriate radical to both sides of the equation.
Step-by-step explanation:
Let's solve for x the following question:
3/4 (x - 16) = 5/4 (2x - 32)
As I told you on the previous exercise:
Step 1: Solve the parenthesis
3/4 x - 48/4 = 10/4 x - 160/4
Step 2: Like terms
3/4x - 10/4x = -160/4 + 48/4
-7/4x = -112/4
Step 3: Simplifying
-7/4x = -28
Step 4: Multiplying by 4 at both sides:
-7/4x * 4 = -28 * 4
-7x = -112
-7x/-7 = -112/-7
x = 16
