The solution is
<u>EXPLANATION</u>
We were given the equations
and
This is a simultaneous equation in and .
But the coefficient of in the second equation is zero. that is why it seems to be absent.
We solve these two equations simultaneously
by putting in to equation (1).
Tis gives;
We add 10 to both sides to get;
we divide through by 4 to get
Hence the solution for the system is
Answer:
f(x) = (x+5)²-26
Step-by-step explanation:
x² + 10x + 25 = 1 + 25
(x+5)² = 26
f(x) = (x+5)²-26
