Question

solve by splitting the middle term: 3x2 - 19x + 28

Sorry I could have done it but my mind is not working at the time.

Answer 1

$\bf{\huge{\star{SOLUTION:-}}}$

____________________

3x² - 19x + 28

Product : 28×3 = 84

Sum : -19

Pair : -12 , -7

Hence,

3x² - 12x -7x + 28

3x( x - 4) -7( x -4)

(3x -7)(x-4)

${x={\frac{7}{3}}}$ , x = 4

Answer 2

Hey!

➡3x^2 - 19x + 28 = 0

=> 3x^2 - 12x - 7x + 28 = 0

=> 3x ( x - 4 ) - 7 ( x - 4 ) = 0

=> ( 3x - 7 ) ( x - 4 ) = 0

x = 7/3

x = 4

Hope this helps ✌✌
