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]
