Answer:
I don't think there are any solutions... (No solution)
Step-by-step explanation:
[tex]x^{2}[/tex]=-7-8
Simplify
[tex]x^{2}[/tex]=-15
To isolate x square both sides:
[tex]\sqrt{x}[/tex]=[tex]\sqrt{-15[/tex]
-15 cannot be squared since it is negative. Therefore, there is no solution.
Answer:
No Real Solutions
Step-by-step explanation:
Move the constants to the left now your equations is [tex]x^{2}[/tex]-7+8=0
Now you calculate -7+8=0 now your equation is [tex]x^{2}[/tex]+1=0
Calculate the discriminant: Determine the number of solutions using the discriminant D=[tex]b^{2}[/tex]-4ac
D=[tex]0^{2}[/tex]-4 x 1 x 1
Simply the expression
D= -4
Since D<0, the quadratic equation has no real solutions
