Hi guys, i need help with these questions, i have attempted the questions myself and just wanted to double check my answers.
convert to standard form
1. y = –3x2 + 2x + 1 ( the answer i got is Y=-3(x+1/3)^2 -2/3) is this correct?
2.y = 4(x + 5)(x – 2) ( i can't figure how to solve this one)
3. Y= -1/2 x^2 ( the answer i got is Y= 2(1-3)+2
can someone please chck my answers and correct me i was wrong.
