Question

Quadratic equation. 5x(x+2)=3.??​

Answer 1

5x(x+2)=3

5x(x)+5x(2)=3

5x

2

+10x=3

5x

2

+10x−3=0

Here,

a=5,b=10,c=−3

Now, by quadratic formula, we have

x=

2×5

−10±

(10)

2

−(4×(5)×(−3))

⇒x=

10

−10±

100+60

⇒x=

10

−10±4

10

⇒x=

5

−5±2

10

Hence for the given expression,

x=

5

−5±2

10

.
