Hey can you me posted picture of question : )

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 :)

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
