Question

see the picture and answer the all questions urgently if you answer the all questions I will mark as brainalist 6 , 7 ,8 , 9

Answer 1

x^2+4x-12=0
x^2+6x-2x-12=0
x(x+6)-2(x+6)=0
(x-2)(x+6)=0
x=2||x=-6;


3x^2-3x-2x+2=0
3x(x-1)-2(x-1)=0
(3x-2)(x-1)=0
x=2/3|| x= 1;

x^2-3=2x
x^2-2x-3=0
x^2-3x+x-3=0
x(x-3)+1(x-3)
(x+1) (x-3)
x=-1
x=3
