Question

solve by factorisation method x square-7x+12=0​

Answer 1

Answer:

There are 2 possible values for x. They are 3 and 4.

Step-by-step explanation:

${x}^{2} - 7x + 12 = 0$

${x}^{2} - 3x - 4x + 12 = 0$

$x(x - 3) - 4( x - 3) = 0$

$( x - 3)( x - 4) = 0$

Therefore,

$x = 3 \: and \: x \: = 4$

Answer 2

x²-7x +12 =0

x² -3x -4x +12 =

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

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

x= 4 and x= 3
