4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
49 Check when:- 4x2-28x+49 = 0 (2x-7)(2x-7) = 0 x = 7/2 and also x = 7/2
4x2 plus 3=11
4x2 + x2 = 8 + x2
y=4x2+3x+8
4x2+20x+25 (2x+5)^2
4x2 + 12x + 5 = (2x + 1)(2x + 5).
8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
x3 + 4x2 + x + 4 = (x + 4)(x2 + 1)
x3 + 4x2 + 6x + 24 = (x2 + 6)(x + 4)
4x2-x+2x2 is 6x2-x when simplified
