Q:

Determine all the real roots of the equation...(x+7)(x^2- 49)=0Drag and drop all real zeros of the equation into the box.(These were the options that I were given.)-49, -14, -7, -4, -3, 0, 3, 4, 7, 14, 49

Accepted Solution

A:
Let's solve it!

So, let's study each factor.

x + 7 = 0 -> x = -7

x² - 49 = 0 -> x² = 49 - > x = ± √49 -> x = ± 7

Final answer: x = 7 and x = -7
