Question

7x^2 +2x -9 middle term splitting ​

Answer 1

Answer:

$7x {}^{2} + 2x - 9$

$7x {}^{2} + 9x - 7x - 9$

$x(7x + 9) - 1(7x + 9)$

$(x - 1)(7x - 9)$

Answer 2

Answer:

7x^2-7x+9x-9

Step-by-step explanation:

Taking 7x and 9x common

7x(x-1)+9(x-1)=0

(7x+9)(x-1)=0

7x+9=0

7x= -9

X= - 9/7

Similarly,

x-1=0

x=1

So the values of x can be 1 or - 9/7
