Answer:
2 real roots
Step-by-step explanation:
To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.
• [tex]b^2-4ac>0[/tex] yields 2 real roots
• [tex]b^2-4ac=0[/tex] yields 1 real root
• [tx]b^2-4ac<0[/tex] yields no real roots
[tex]3x^2-10=0[/tex] where a=3, b=0, and c=-10
[tex]b^2-4ac=(0)^2-4(3)(-10)=0+120=120>0)[/tex] has 2 real roots
