To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:
Now square root both sides to get
The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:
and
X= -2 is not the solution to the equation.
explanation: if you plug in -2 into -3–7, you get -1, and if you plug -2 into 5(x-1) you get -18.
