Answer:
x² - 9x - 9 = 0
Explanation:
The standard form of the quadratic equation is:
ax² + bx + c = 0
This means that we would need all the terms on one side of the equation and a zero on the other.
This can be done as follows:
x² - 6x - 7 = 3x + 2
Subtract (3x+2) from both sides as follows:
x² - 6x - 7 = 3x + 2
x² - 6x - 7 - 3x - 2 = 3x + 2 - 3x - 2
x² - 6x - 7 - 3x - 2 = 0
Now, combine like terms to get the final expression in standard form:
x² - 9x - 9 = 0
Hope this helps :)
