Question

solve for x: 5x^2 + 6x +1 = 0
Class 10 Maths​

Answer 1

Answer:

Here, 5x² +6x +1=0

Or,5x² +5x +x +1=0

Or,5x(x+1)+1(x+1)=0

Or,(x+1)(5x+1)=0

Now Either x+1=0

Or, x=-1

Or, 5x+1=0

Or,5x=-1

Or, x=-1/5

Therefore, x=-1,-1/5

Answer 2

Answer:

(x= -1/5) or (x= -1)

Step-by-step explanation:

5x^2 + 6x +1 = 0

by middle term split

5x^2 + 5x + x + 1 = 0

5x(x + 1) +1(x + 1)

taking common

(5x + 1) (x + 1)

so, x = -1/5 or x = -1
