2x2-9x+4 = (2x-1)(x-4) when factored
6-18= -12 -12/6= -2 -2x2= -4 answer= -4
For x = -4 2x2 + x = 2 (-4)2 + (-4) = 32 - 4 = 28
Order of operations--Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. 15-2x2 (fifteen minus two times two) 15-4 11
2 sqared is 4 so 2x2 sqared is 4
2x2=4 X -2=-8
The outcome is zero.

2x2 - 16x32 2x2=4-16= -12x32= -384
-1/2
Minus 61 (-61)
3x2 - 5x2 = -2x2
If: 2x2 = 4 Then: x = the square root of 2
