Answer:
28
Step-by-step explanation:
Move the 10x to the other side of the equal sign by subtracting it from both sides.
9x^2 + 2 - 10 = 0
Plug the numbers into the formula b^2 - 4(ac)
Substitute in the values of a , b, and c.
( − 10 )^2 − 4( 9 ⋅ 2 )
Simplify each term until it cant be reduced anymore
