Question

1) 2x²-10x+12=0

2) x²-2x-15=0

Answer 1

Answer:

2x²- 10x +12

Step-by-step explanation:

2x²- 6x -4x + 12

2x (x -3) -4 (x -3)

( x -3) (2x -4)

x²-2x -15

x²-5x +3x -15

x (x -5) +3 (x -5)

(x-5) (x +3)

Answer 2

Answer:

2x2-10x+12=0

2(x2-5x+6)=0

x2-5x+6=0

x2-3x-2x+6=0

x(x-3)-2(x-3)=0

(x-2)(x-3)=0

x=2 ; x=3

Step-by-step explanation:

x2-2x-15=0

x2-5x+3x-15=0

x(x-5)+3(x-5)=0

(x+3)(x-5)=0

x=-3 ; x=5
