Answer:
[tex]x^{2} +7x-30=0[/tex]
Step-by-step explanation:
So all we need to do is create a quadratic equation that has x equal to 3 and -10. So lets solve it backwards:
[tex]x=-10, x=3[/tex]
Start with the given solutions.
[tex]x-3=0, \ x+10=0[/tex]
Get everything to one side so that only 0 remains on the right side (for both equations).
[tex](x-3)(x+10)=0[/tex]
Use the zero product property to combine the equations.
[tex]x^{2} +7x-30=0[/tex]
FOIL out the left side.
Solve that equation, and we find that we get x = 3 and x = -10, so [tex]x^{2} +7x-30=0[/tex] is the correct answer
Answer: The answer is x2-7x-30. When you multipy 3 and 10 (from x=3 and x=10), you should get a -7x and a -30 leaving you with the equation x2-7x-30.
