These questions are dark but if you zoom in its possible to see

23. To complete the square you divide the x term by 2 and square it

(6/2)^2 = 9 so we have

(X+3)^2 = 2

then square root both side and get x by itself

x = √2 + 3

x = 4.41 , 1.585

A

24. x^2 - 4x = 1

Factor

X(x - 4) = 1

x = 4.23 and -.24

A

25. x^2 +3x = 4

factor

x(x + 3) = 4

solve

x =  -4 or 1

A

26. X^2 +5x = 10

Factor

x(x +5) = 10

solve

x = 1.53 and -6.53

A
