因为2a2-3a=6,
所以4a2-6a+100=2(2a2-3a)+100=2×6+100=112,
故答案为:112.
所以4a2-6a+100=2(2a2-3a)+100=2×6+100=112,
故答案为:112.
若3a2-a-2=0,则5+2a-6a2=______.
若实数a满足a2-2a-1=0,则3a2-6a+5=______.
若实数a满足a2-2a=3,则3a2-6a-8的值为______.
若a2+2a=1,则2a2+4a-1=______.
若a2+a=0,则2a2+2a+2013=______.
若a2+a=0,则2a2+2a+2007的值为______.
若实数a满足a2-2a+1=0,则2a2-4a+5=______.
已知a2+2a+1=0,则2a2+4a-3的值为______.
