LESSON: SOLVING QUADRATICS EQUATIONS solve the equation. check your solutions.

1.) x^2+9=0

2.) x^2-4= -11

Step-by-step explanation:

x² + 9= 0

(move internode)

x²= -9 (heve no solution and parentheses )

if the number is negative and we are asked to find the root of n (if n is an even number). then it has no solution. example that have solution:

x²= 9

x = √9

x= 3

because, (3)²= (3) × (3)

= 9

or it could be: (-3)²

= 9

You must use parentheses if you want to convert it to the square root

2. x² - 4= -11

(move internode)

x²= -11 + 4

x²= -7 (haven't no solution because 7 is not the number of the square root and there are no brackets)

hi! i think the answer is 1/2 : )

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
