2x² − 7x + 5
3x2 - 7x = -2 3x2 - 7x + 2 = 0 3x2 - 6x - x + 2 = 0 3x(x - 2) - 1(x - 2) = 0 (x - 2)(3x - 1) = 0 so x - 2 = 0 or 3x - 1 = 0 so x = 2 or x = 1/3
Let the number be x: 7x-6 = -20 7x = -20+6 7x = -14 x = -2
(12x3 + 14x2 + 14x + 2)/(4x + 2) simplify= (6x3 + 7x2 + 7x + 1)/(2x + 1)1. 6x3 + 7x2 - 3x2(2x + 1) = 6x3 - 6x3 + 7x2 - 3x2 = 4x2; bring down 7x2. 4x2 + 7x - 2x(2x + 1) = 4x2 - 4x2 + 7x - 2x = 5x bring down 13. 5x + 1 - 2(2x + 1) = 5x - 4x + 1 - 2 = x - 1 the reminderThus, (6x3 + 7x2 + 7x + 1)/(2x + 1) = 3x2 + 2x + 2 + (x - 1)/(2x + 1)and(12x3 + 14x2 + 14x + 2)/(4x + 2) = 3x2 + 2x + 2 + (2x - 2)/(4x + 2).
you begin with -7x+y=-20 and 9x-3y=36 7x-7x+y=-20+7x (add 7x to both sides) y=7x-20 (simplify) 9x-9x-3y=36-9x (subtract 9x from both sides) -3y/-3=36/-3-9x/-3 (divide both sides by -3) y=3x-12 (simplify) y=y so 7x-20=3x-12 7x+20-20=3x-12+20 (add 20 to both sides) 7x=3x+8 (simplify) 7x-3x=3x-3x+8 (add 3x to both sides) 4x=8 (simplify) 4x/4=8/4 (divide by 4 on both sides) x=2 (simplify) 9(2)-3y=36 (plug in 2 for x) 18-3y=36 (simplify) 18-18-3y=36-18 (subtract 18 from both sides) -3y=18 (simplify) -3y/-3=18/-3 (divide by -3 on both sides) y=-6 (simplify) the point is 2,-6 (x,y)
3x2 - 7x - 20 = (3x + 5)(x - 4)
(x + 4)(3x - 5)
3x2-7x+4 = (3x-4)(x-1) when factored
3x2-7x-20 = (3x+5)(x-4) when factored
(3x - 5)(x + 4)
(3x - 4)(x - 1)
-29
(21x3-23x2-76x-32)/(7x+4) = [3x2(7x4) -5x(7x+4)-8(7x+4)]/(7x+4)=3x2-5x-8
If that's +7x - 6, the answer is (x + 3)(3x - 2)
It is -2*(3x2 - 7)*(x3 - 7x)-3
3x2 - 7x + 2 = 3x2 - 6x - x + 2 = 3x(x - 2) - 1(x - 2) = (3x - 1)(x - 2) So x = 1/3 or x = 2
If you mean 3x2-7x+x = -4 then there are no solutions because the discriminant of the quadratic equation is less than zero.
