Answer:
solve for x
x=2
Step-by-step explanation:
x2-20x-17=-53
reorder like terms x2= 2x 2x=20x-17=-53
collect like terms 2x-20x=-18x -18x-17=-53
move constant to the right hand side and change its sign -18x=-53+17
calculate the sum -53+17= -36 -18x=-36
divide both sides by -18 -18x÷-18= x -36÷-18=2
