2x^2 + 6x - 9 = 3x^2 - 11x - 7

Subtract 2x^2 from both sides
6x - 9 = x^2 - 11x - 7

Substract 6x from both sides
-9 = x^2 - 17x - 7

Add 9 to both sides
0 = x^2 - 17x + 2

a = 1
b = -17
c = 2

If x − 3 = 1, then what is the value of x² − 3x − 1 ?
Kruka [31]
Let's find x. This will allow us to find the value of the second expression.
x - 3 = 1
x = 4

Now, we can simply plug this x-value into the second expression to obtain 4^2 - 3(4) - 1 = 3.

Thus, our answer is 3.
