21x3-35x2+14x = 7x(3x2-5x+2)
5x^2 + 14x - 3x^2 - 9 = 2x^2 + 14x - 9
5x2 - 14x + 8 = 5x2 - 10x - 4x + 8 = 5x(x-2) - 4(x-2) = (5x-4)*(x-2)
5x2+14x-3 -15. 15*-15x2-x+15x-3[5xx x] [3*5x 3]x(5x-1)+3(5x-3)Answer: (5x-1)(x+3)
(5x - 1)(x + 3)5x2 + 14x - 3= 5x2 + 15x - x - 3= 5x(x + 3) - 1(x + 3)= (5x - 1)(x + 3)
(x - 2)(5x + 24)
5x+8x+3x-2x = 14x
yes, and it is 14x
It is 14x+4 simplified
21x3-35x2+14x = 7x(3x2-5x+2)
5x^2 + 14x - 3x^2 - 9 = 2x^2 + 14x - 9
5x2 - 14x + 8 = 5x2 - 10x - 4x + 8 = 5x(x-2) - 4(x-2) = (5x-4)*(x-2)
5x2+14x-3 -15. 15*-15x2-x+15x-3[5xx x] [3*5x 3]x(5x-1)+3(5x-3)Answer: (5x-1)(x+3)
(5x - 1)(x + 3)5x2 + 14x - 3= 5x2 + 15x - x - 3= 5x(x + 3) - 1(x + 3)= (5x - 1)(x + 3)
(5x - 1)(x + 3)
15x2 + 58x + 48= 15x2 + 18x + 40x + 48= 3x(5x + 6) + 8(5x + 6)= (3x + 8)(5x + 6)
5x2+14x-24=0 Delta = 142-4x5x(-24)=676=262 X = (-14 + sqrt(676))/(2*5) = 12/10 = 6/5 or X = (-14 - sqrt(676))/(2*5) = -40/10 = -4
