How to factor 3x2 plus 8x plus 5?
(x + 1)(3x + 5)
X2 - 3 equals -3x2 plus 8x?
In general, no.
How many roots does 3x2 plus 8x plus 3 have?
two negative
X2 plus 8x equals -3x2 plus 5?
x2+8x = -3x2+5 4x2+8x-5 = 0 (2x+5)(2x-1) = 0 x = -5/2 or x = 1/2
How do you factor 3xsqrd plus 8x-8?
3x2 + 8x - 8 doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (-4 plus or minus 2 times the square root of 10) divided by three.x = 0.7748517734455863x = -3.441518440112253
How do you factor an equation with a squared number in it. Example 5 minus 8x plus 3 times x squared?
5 - 8x + 3x2 = 3x2 - 8x + 5 (since the sign of the second term is negative, then 5 can be factored as (-1)(-5)) = (3x - )(x - ) (try to put 1 or 5 to the empty places, in order to obtain -8x) = (3x - 5)(x - 1)
Put the equation in the form ax2 plus bx plus c equals 0 x2-3 equals 3x2 plus 8x?
2x^2 + 8x + 3 = 0
What is (6(3x2) plus 8x-3) plus (3(3x2)-7x plus 2) simplified?
The sum 6 (3x^2) + 8x -3 plus 3 (3x^2) - 7x + 2 = 27 x^2 + x -1
What is the answer to 24x3-5x2-48x-8 divided by 8x plus 4?
If you notice, 8x + 4 = 4(2x + 1), but there is an odd coefficient for x2, so there is guaranteed to be some remainder (that is 8x + 4 is not a factor of the polynomial): (24x3 - 5x2 - 48x - 8) ÷ (8x + 4) = 3x2 - 2x - 5 - (x2 - 12)/(8x + 4)
What is 3x2 plus 8x plus 5?
= (3x + 5)(x + 1) so x = -5/3 or -1
Does this have a factor x2-8x plus 6?
That does not factor neatly.
How many times does 3x2 plus 8x plus 5 touch or cross the x axis?
If you mean: 3x2+8+5 = 0 Then it crosses the x axis at points -1 and -5/3
