Step 1
Given: 10x2+30x20=0
Multiplying both sides with -1
We get,
10x230x+20=0
By Using quadratic formula
x=b±b24ac2a
we get,
x=30±3024×10×202×10
x=30±1020
x=4020, x=2020
Thus we get the value of x as x=2, 1

Step 1
Given:
10x2+30x20=0
10(x23x+2)=0
Dividing both sides by 10 we get
x23x+2=0
x2x2x+2=0
x(x1)2(x1)=0
(x2)(x1)=0
x2=0
x=2 NKS x1=0
x=1
