The value of that expression is positive whenever 'x' is negative.
Yes if x=5 then 4(5)= 20 and 15+5=20
I think the answer is D because its multiplying by 2 each time
Answer:
25x² − 20x + 4
Explanation:
(5x − 2)²
= (5x + −2)(5x + −2)
= (5x)(5x) + (5x)(−2) + (−2)(5x) + (−2)(−2)
= 25x² − 10x − 10x + 4
= 25x² − 20x + 4
