c). x²-15x+50 = 0 d). x²+15x+50 = 0
Plz help me with this answer !!!

Answer 1

Answer: x² + 15x + 50

Step-by-step explanation:

Since all the options is a quadratic = 0, then let's write the given equation in that form by making 0 the subject of the equation:

                      −x² = 15x+50              [add x² to both sides]

               -x² + x² = x² + 15x + 50       [simplify]

 x² + 15x + 50 = 0   (OPTION D)
