Question

• Solve the following quadratic equations by factorisation.
6x²-x-2= 0

6x²+40-31x= 0

6x+x² = -5

x²-9 = 0

100x²-20x = -1

​

Answer 1

Step-by-step explanation:

1 . 6x^2-4x+3x-2=0

2x(3x-2)+1(3x-2)

x=2/3 or x=-1/2

5. 100x^2-20x+1=0

100x^2-10x-10x+1=0

10x(10x-1)-1(10x-1)=0

x=1/10 or x=1/10

other you can do same like this

because mathematics can't be practice without doing it by own
