Determine all the real roots of the (x+7)(x^2- 49)=0 drag 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

Answers

The given answer would be five
-3x + 7 = 4
-3x = -3
x = 1

4(1) - 4
4-4
0
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 x = 7 and x = -7


Do you know the answer?
