Question

Hey can you please help me posted picture of question :)

Answer 1

Transposing all the values on the right side to the left we get

C. x^2 -9x -9

Answer 2

Answer:
x² - 9x - 9 = 0

Step-by-step 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 :)
