What is 8x cubed plus 4x squared plus 6x plus 3?
8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
What is the answer to this question when you factorise 6x 2 plus 7x-3?
If you mean: 6x^2 +7x-3 then it is (2x+3)(3x-1) when factored
What is the quotient and remainder when 8x cubed minus 24x plus 9 is divided by 2x minus 3?
4x2 + 6x - 3 (with no remainder)
What is 4x2 plus 3 equals?
4x2 plus 3=11
Factorise x2-6x plus 9?
x*2 - 6x + 9 x*2 -3x -3x +9 x(x-3) -3(x-3) (x-3)(x-3) Note also that x*2 - 6x + 9 is of the form a*2 -2ab + b*2 and so the factors are (x-3) and (x-3)
What is 8x cubed plus 4x squared plus 6x plus 3?
8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
Factor 8x cubed plus 4x squared plus 6x plus 3?
This is how I did it:8x3+4x2+6x+3[8x3+4x2]+[6x+3][(4x2)(2x+1)]+[(3)(2x+1)]....as you can see, this is in the general form of ab+cb, which factored is b(a+c), so:(2x+1)(4x2+3)
How do you factorise 4x2 plus 5x - 6?
(4x-3)(x+2)
What is the answer to this question when you factorise 6x 2 plus 7x-3?
If you mean: 6x^2 +7x-3 then it is (2x+3)(3x-1) when factored
Need equivalent expression for 4x squared minus 12x plus 9?
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
How do you factorise 6 x cubed plus 3 x?
6x^3 + 3x = 3x(2x^2 + 1)
How do you factorise 2xy - 6x plus 7y -21?
2x(y - 3) + 7(y - 3) = (2x + 7)(y - 3)
Factorise 6x plus 9x cubed?
6x + 9x^3 = 3x*(2 + 3x^2)
What is the degree of 6x5-4x2 plus 2x3-3 plus x?
(6x^5-4x^2)+(2x^3-3) = 6x^5-4x^2+2x^3-3 The grestest exponent is 5, which is the degree of the above expression.
How do you factorise 4xsquared 8x 3?
4x2+8x+3 ------> (2x+3)(2x+1)
What is the quotient and remainder when 8x cubed minus 24x plus 9 is divided by 2x minus 3?
4x2 + 6x - 3 (with no remainder)
X2 plus 6x equals - 4x2 plus 2?
5x^2 + 6x - 2 doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (-3 plus or minus the square root of 19) divided by 5. x = 0.2717797887081348 x = -1.4717797887081348
