Natural numbers include all the whole numbers, and even 0... they can not be fractions, or negative numbers.
By the zero product property, either (x^2 -4x + 4 = 0
<span>which easily factors into (x-2)(x-2) and thus gives two roots of 2 and 2 </span>
<span>or </span>
<span>( x^2 +3x -10) = 0 which also factors to give 2 and -5 </span>
<span>so all 4 roots : 2,2,2, -5 </span>
<span>and for your answer : { 2 and -5 } </span>
Answer: B
Step-by-step explanation:
Answer:
x=-10/3
Step-by-step explanation:
(2x+4)=-4(-2x-6)
distribute -4 to (-2x-6) by multiplying
negative multiplied by a negative is a positive
8x+24=2x+4
subtract 24 from each side
8x=2x-20
subtract 2x from each side 6x=-20
divide both sides by 6
-20/6
simply to -10/3 or -3 1/3 or -3.3
x=-10/3
