y=4(x+3)2+5 in standard form
just multiply it out, 4*(x+3)*2 or 8(x+3) is 8x + 24, and then plus 5 so the final answer is 8x + 29
edit: Accidentally wrote (x+2) isntead of (x+3) which screwed up the answer
y=4(x+3)2+5
First we distribute 4
y=(4x+12)2+5
Now we can rewrite that as
y=2(4x+12)+5
Now we can distribute 2
y=8x+24+5
24+5=29
y=8x+29
