Question

Find the required relation
1) 5x^ 2 +6x+1
2) 7x^2-6x-1
3) 4x^2 -4x-3
4) 100x^2+25x +1

Plz plz solve it
I will mark it as brainlest

Answer 1

Step-by-step explanation:

1) 5x^2+6x+1

5x^2+5x+1x+1

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

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

x=-1/5 or -1

2)7x^2-6x-1

7x^2-7x+1x-1=0

7x(x-1)+1(x-1)=0

(7x+1)(x-1)=0

x=-1/7 or +1

4x^2-4x-3

4x^2+2x-6x-3=0

2x(2x+1)-3(2x+1)=0

(2x-3)(2x+1)=0

x=3/2 or -1/2

100x2+25x 

Final result :

25x • (4x + 1)

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "x2"   was replaced by   "x^2". 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

(22•52x2) + 25x

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   100x2 + 25x  =   25x • (4x + 1) 

Final result :

25x • (4x + 1)
