Step-by-step explanation:
1. 5x-3=0
=>x=3/5
2. 9x²-4=0
=> (3x+4)(3x-4)=0
=> x=3/4 & x= -3/4
3. 5x²-9=0
=> (√5x+9)(√5x-9)=0
=> x=9/√5 &. x= -9/√5
4. (x+1)(3x+2)=0
=> x= -1 & x= -3/2
5. (x+2)(x-3)(2x-7)=0
=> x= -2 , x=3 & x=7/2
In all the above question you have to just make an quadratic and linear equation and solve by putting it equal to zero.
