How do you factor 250z4-2z?
2z(5z - 1)(25z^2 + 5z + 1)
-3 X -2Z - 7 equals?
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
5x minus 2z?
3xz
What is the simplified form of 2z - 14z plus 45 over 2z plus z-30?
-2z + 3
What is 2z-28?
2z-28 = -26
what is 16z-24=8(2z-3)=?
16(2z-3)
What is y2-2zy-2y-2z-3 factored?
(1) y2-2zy-2y-2z-3 = y2 -2y (z+1) - (2z+3) Delta = [-(z+1)]2 - (- (2z+3)) = z2+2z+1+2z+3= z2+2z+4 = (z+2)2 (If used the reduced form as b=-2(z+1) is even, b'=-(z+1) and delta=b'2-ac) y=(z+1) ± (z+2) so y = 2z+3 or y =-1 So the (1) can be written (y-2z-3)(y+1)
2z plus 9.75-7z equals -5.15?
2z+9.75-7z=-5.15
What is the LCD of 2z-4 and 2z-10?
2(z-2)(z-5)
What is the absolute value of 2z-3 equals 0?
2z-3 equalls 0 and 2z equalls 3 and z equalls 3/2 therefore z = 1.5
What is 2z plus 17 equals 21?
2z+17=21 subtract 17 from both sides. 2z=4 divide both sides by 2 z=2
What is the general form of the perpendicular bisector equation of the line segment of z 2z and 3z 8z?
Mid-point: (3z+z)/2, (2z+8z)/2 = (2z, 5z) Slope: (8z-2z)/(3z-z) = 6z/2z = 3 Perpendicular slope: -1/3 Equation: y -5z = -1/3(x -2z) => y = -1/3x+2z/3+5z => y = -1/3x+17z/3 General form of the bisector equation: x+3y-17z = 0
