35 points ill literally love you forever if you help me with this x^2-18x=40 by Completing the Square
pls show the steps!!

Step-by-step explanation:

divide by 2 and square it

y+axSQUARED +bx+ c >(b/2)squared +d

2 ) add and subtract d to the equation

y = (axSQUARED +bx +d ) + c -d

factor the first part of the equation to match the vertex form and simplify

y= a(x-h)SQUARED + c- d

Y = a ( x - h SQUARED + k

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
