How do you factorise quadratics the second method like I can’t get my head around it one of the questions are 8x*2 +5x-2 and I put *2 for squared as I can’t type it?

So you would have to use the ax^2 +bx + c =0 formula x = -b+/- square root ( b^2 -4ac) / 2a You then sub in the numbers accordingly to the above equation so a = 8 b = 5 c = -2 Then you should get positive x value and a negative x value
