x=2,1

Explanation:

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±30241020210
x=30±1020
x=4020,x=2020
Thus we get the value of x as x=2,1

x=2
x=1

Explanation:

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

x1=0

x=1
