Answer:
Step-by-step explanation:
Let's FOIL out both sides and then see where we are after that:
[tex]x^2-5x+6=x^2+3x+2[/tex]
Let's combine like terms now and get everything on one side of the equals sign and set the polynomial equal to 0 to solve for x:
0 = 8x - 4 and we can factor out a 4 to give us:
0 = 4(2x - 1)
Either 4 = 0 or 2x - 1 = 0. Well it's obvious that 4 does not equal 0, so 2x-1 must equal 0. Then
2x = 1 so
x = 1/2 or choice A on the left.
Answer:
The answer to your question is the letter A) 0.5
Step-by-step explanation:
Data
Equation (x - 2)(x - 3) = (x + 1)(x + 2)
Process
1.- Expand
x² - 3x - 2x + 6 = x² + 2x + x + 2
2.- Simplify like terms
x² - 5x + 6 = x² + 3x + 2
3.- Group like terms
x² - x² - 5x - 3x = 2 - 6
4.- Solve for x
-8x = -4
x = -4/-8
x = 1/2
x = 0.5
