Step-by-step explanation:
Answer:
this seems hard to do
Step-by-step explanation:
Answer:The roots are:Explanation: First we would need to put the equation in standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
9x² + 6x + 1 = 8
Subtract 8 from both sides and combine like terms to reach the following:
9x² + 6x - 7 = 0
By comparison:
a = 9
b = 6
c = -7
Now, to get the roots, we would need to use the quadratic formula attached in the images.
By substitution, we would find that:
either x =
or x =
