What is the name of this function 4y plus 8 equal to 3x to the power of 2 minus 2x plus 1?
if you rearrange it, it becomes 4y + 8 = 3x2 -2x +1 4y = 3x2 -2x -7 y= (3x2 -2x -7)/4 which is a parabola
What is 3x squared plus 2x minus 8 equals 0?
3x2 + 2x - 8 = 0 is a quadratic equation.
Factor this polynomial completely 3x2 plus 2x - 8?
3x2 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x+2) - 4(x+2) = (3x-4)*(x+2)
4x-2 plus 5 equals 2x plus 8?
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
How do you solve 3x squared plus 2x equals 16?
3x2 + 2x = 16 ∴ 3x2 + 2x - 16 = 0 ∴ 3x2 - 6x + 8x - 16 = 0 ∴ 3x(x - 2) + 8(x - 2) = 0 ∴ (3x + 8)(x - 2) = 0 ∴ x ∈ {-8/3, 2}
What is the answer for 2x plus 8 plus x equals 2x plus 15?
2x + 8 + x = 2x + 15 simplify 2x to both sides since they have the same sign8 + x = 15 subtract 8 to both sidesx = 7
Simplify this expression. 7x plus 8(2y plus 2x)?
It is 16y+23x simplified

3x2 - 2x - 8?
(3x + 4)(x - 2)
What is the solution to 3x squared -2x-8?
3x2-2x-8 = (3x+4)(x-2) when factored
What are the 2 solutions for x if 3x2 plus 2x-8 equals 0?
3x2+2x-8=0 Delta = 22-4*3*-8= 100 So x = (-2 + sqrt(100))/(2*3) or x = (-2 - sqrt(100))/(2*3) x = 4/3 or x=-2
Factor expression 3x2 plus 48x plus 192?
