Question

factorise a quadiratic polynomial=35x^2+12x+1​

Answer 1

Answer:

$35 {x}^{2} + 12x + 1 = 0 \\ = 35 {x}^{2} + 7x + 5x + 1 = 0 \\ = 7x(5x + 1) + 1(5x + 1) = 0 \\ = (5x + 1)(7x + 1) = 0 \\ = x = \frac{ - 1}{5} \: \: and \: \: \frac{ - 1}{7} \: \: answer$

Hey! Mate Here is your solution. Thanks

Answer 2

Answer:

x=-1/7 and -1/5

Step-by-step explanation:

35x²+12x+1

using the method of splitting the middle term

35x²+7x+5x+1

7x(5x+1)+1(5x+1)

(7x+1)(5x+1)

as (7x+1) and (5x+1) are factors of the equation

therefore  (7x+1) =0 and (5x+1)=0

7x+1=0

x=-1/7

5x+1=0

x=-1/5

hope it helps:)
