Question

X^2 -9 = -15 i got decimals please help me

Answer 1

Equation: x² - 9 = -15

Step-by-step solution:

• Move -9 to right side
-> x² = -15 + 9

• Solve
-> x² = -6

• Root of both sides
-> x = √-6
This is wrong because √-1 = imaginary number and it doesn't look like you're dealing with imaginary numbers so check the equation again

Answer 2

Answer:

sqrt 24

Step-by-step explanation:

x^2-9=-15

x^2-9+9=-15+9

x^2=24

x=sqrt 24
