Answer 1

@Hero

Answer 2

try it by using fectorization method

Answer 3

the above equation will become
2x2 + x -1 =2
2x2 + x -1 - 2 = 0
2x2 + x - 3 = 0

Answer 4

then from the form ax^2 + bx + c = 0 find your AC
what are the factors of AC that add up to B , pay attention to the signs

Answer 5

using -2 and +3
2x^2 -2x + 3x -3 = 0 then group and factor
2x(x -1) +3(x-1)= 0 use the distributive property with the common factor
(2x + 3)( x - 1) = 0
to get a product of zero then one factor must be zero
2x - 3 = 0 or x - 1 = 0
