Answer:

D:  x = -4

Step-by-step explanation:

Given equation:

(2x - 10)(3x + 12) = 0

Therefore:

⇒ 2x - 10 = 0

⇒ 2x = 10

⇒ x = 5

And:

⇒ 3x + 12 = 0

⇒ 3x = -12

⇒ x = -4

So the possible solutions of the equation are x = 5 or x = -4

Answer:

D: r = -4

Explanation:

[tex]\rightarrow \sf (2x-10)(3x+12)=0[/tex]

set to zero

[tex]\rightarrow \sf 2x-10=0, \:3x+12=0[/tex]

change sides

[tex]\rightarrow \sf 2x=10, \:3x=-12[/tex]

simplify

[tex]\sf \rightarrow x=5,\:x=-4[/tex]
