[tex]6 - 10x = 2 \\ - 10x = 2 - 6 \\ 10x = 4 \\ x = 4 \div 10[/tex]
thus x will be 2/5
Answer:
D = 76.
Step-by-step explanation:
Given : 3x² - 10x = -2.
To find : What is the discrimination.
Solution : We have given 3x² - 10x = -2.
By the formula : ax² + bx + c = 0.
Discrimination (D) = b² - 4ac.
Here, a = 3 , b = -10 , c= 2.
D = (-10)² - 4(3) (2).
D = 100 - 24.
D = 76.
Therefore, D = 76.
