A. completing the square: x∧2+6x+9=0

b. solve for x: 2x∧2+6=24

this is for a freind there 86 pionts

A = x  =  − 3

B = x  =  3 ,  − 3

Step-by-step explanation:

For A = Use the formula  ( b/2^2 ) in order to create a new term. Solve for  x  by using this term to complete the square.

For B = Isolate the variable by dividing each side by factors that don't contain the variable.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.
