Question

please any tell all the answers I will mark him or her as brainliest​

Answer 1

Answer:

I didn't do second part (splitting wala)

Sorry for that....

Answer 2

Answer:

1. 3x -2 =0

   3x = 2

     x =2/3

2.7x + 14 =0

  7x = -14

   x = -14 / 7

   x = -2

3. 2x - √5 = 0

   2x = √5

     x = √5/2

4. √9 -√7x = 0

   -√7x = -√9

      x = √9/√7

5. (10/√2)  + √5x = 0

   √5x = -(10/√2)

     x = -10 /√10

     x = -√10

6. 5x - 75/2 = 0

   5x = 75/2

    x = 75/10

    x = 7.5

Middle term spilliting

1.  $5x^{2} + 7x + 2 = 0$

  $5x^{2} + 5x + 2x + 2=0 \\ 5x( x + 1) + 2( x + 1)=0\\ ( x + 1) ( 5x + 2 )=0$

x + 1 = 0              5x + 2 = 0

x = -1                    x = -2/5

$2. 2x^{2} + 9x + 7 = 0\\2x^{2} +2x +7x + 7 \\ 2x( x+1) +7( x+1) =0\\( x+1) (2x + 7)=0$

x +1 =0            2x + 7 = 0

x = -1                x = -7 /2

3.  $15x^{2} + 8x + 1$

   $15x^{2} + 5x + 3x +1 \\ 5x(3x+1) +1 (3x+1) \\(5x+1) ( 3x + 1)$

  5x + 1 = 0                       3x + 1 = 0

  x = -1 / 5                          x = -1 /3

4. $9x^{2} - 6x -3=0$

  $9x^{2} - 9x + 3x -3=0 \\9x (x-1) +3 ( x-1)=0\\(x-1) (9x+3)=0$

x-1 = 0             9x + 3 =0

x = 1                  x =  -3/9 = -1/3

5. $x^{2}+ 5x -6=0$

  $x^{2} +6x -x -6=0\\x(x+6) -1(x+6) =0\\(x+6) (x-1)=0$

x+6 =0               x -1 =0

x = -6                x = 1
