4x2 + 12x + 5 = (2x + 1)(2x + 5).
4x2+12x = 4x(x+3) when factored
64
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
4x2 is 8+ 12x + 3 collect like terms, 8+3= 11, 12x+11 to solve for x, transpose the 11 to the other side of the = sign, 12x=-11, divide by 12, x=-11/12
4x2 + 12x + 5 = (2x + 1)(2x + 5).
4x2 = -12x, divide both sides by 4x: x = -3
false!
4x2+12x = 4x(x+3) when factored
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
12x * 4x2 = 48x3

4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
4x2-42x+110 = (2x-10)(2x-11) when factored
4x2 is 8+ 12x + 3 collect like terms, 8+3= 11, 12x+11 to solve for x, transpose the 11 to the other side of the = sign, 12x=-11, divide by 12, x=-11/12
c = 25 4x2 + 20x + 25 (2x + 5)(2x + 5)
