(20x + 3)(1x + 1)
20x2 = 41x+9 20x2-41x-9 = 0 (5x+1)(4x-9) = 0 Therefore: x = -1/5 or x = 9/4
2(5x + 3y)(2x + 5y)
(2x+1)(2x+3) when factored
20x2 + 22xy + 6y2 = 20x2 + 10xy + 12xy + 6y2 = 10x(2x + y) + 6y(2x + y) = (2x + y)(10x + 6y) = 2(2x + y)(5x + 3y)
20x2=40
X3 - 20X2 + 19Xfactor out an XX(X2 - 20X + 19)what two factors of 19 add up to - 20?X(X - 1)(X - 19)============ fully factored
20x2 - 3x + 10 does not have any real factors.
20X2 + 3010(2X2 + 3)============That's as much factoring as can be done here.
20 x 2 = 40.3 x 8 = 2440 + 24 = 6464 + 2 = 66The answer is 66.
Divide by x: x(x2 - 20x + 19); = x(x -1)(x - 19)
