find the Quadratic Inequality or Not Inequality.

1. 2x²<=8
2. 5(5x + 7) > 10
3. 7x²-15>7(2x²+5x)
4. 0.1 x²+2.3x<-4
5. 2x²-5<=2x²

Solve each quadratic inequality

1. x²+6x+9>0
2. x²+10x+25<=0
3. x²-2x-0<=0
4. x²-16<0
5. x²+3x>0

need with solution pls
and also i need this now.
thank you in advance.​
