in such cases where 2 line intersect each other, opposite angels are equal
so
2x+2 = 3x - 52
now subtracting 2 from both side
2x +2 -2 = 3x - 52 - 2
2x = 3x - 54
subtracting 3x from both side
2x -3x = 3x -54 - 3x
-x = -54
drividing by -1 both side
-x/-1 = -54/-1
x = 54

Answer:
C. 5x^2(x - 3)(x + 7)
Step-by-step explanation:
When 5x^2 is factored out, you have ...
5x^2(x^2 +4x -21)
To factor the remaining quadratic, you need two numbers with a sum of 4 and a product of -21. Those would be 7, -3. This tells you the fully factored form is ...
5x^2(x -3)(x +7) . . . . matches choice C
