Answer

a=  −bx−c  / x2

Step-by-step explanation:

ax2+bx+c=0

Step 1: Add -bx to both sides.

ax2+bx+c+−bx=0+−bx

ax2+c=−bx

Step 2: Add -c to both sides.

ax2+c+−c=−bx+−c

ax2=−bx−c

Step 3: Divide both sides by x^2.

ax2

x2

=

−bx−c

a=

hey, i have this question for algebra nation and i have no clue how to work this problem out... can you please help me?
irina1246 [14]
In algebra the notation is basically just a number, for example, 10, and we take it to the 10th power, you just take the decimal at the end of the 10 and move it 10 spaces to the right, if the number is negative you will move the decimal to the left 10 spaces, the 10th power is a variable and is different with every question
