Question

2(3x^2-5)+10=-30 pls answer ​

Answer 1

Answer:

√5

Step-by-step explanation:

2(3x^2+5)+10=30

6x^2-10+10=30

6x^2=30

divide both sides by 6

x^2= 5

taking square root of both sides

x=√5

Answer 2

2( 3x² - 5)+ 10 = - 30

6x² - 10 + 10 = - 30

6x² = - 30

x² = -5

x = $\sqrt{ - 5}$

x = root 5i
