What is the foiled version of 3x2 - 24x plus 48?
(3x-12)(x-4)
What value of c makes 9x2 plus 24x plus c a perfect square?
16? using 16, you have (3x2 + 4)(3x2 + 4) = 9x2 + 24x + 16
How can you solve 3x2 plus 24x equals 0?
x=-.25.
What is the x-intercept of negative 3x squared plus 24x minus 19?
The idea is to solve the equation -3x2 + 24x - 19 = 0. You can use the quadratic formula for this, using a = -3, b = 24, c = 19. Or complete the square since dividing by -3 will give us 8x, an even coefficient. -3x2 + 24x - 19 = 0 (add and subtract 48 to the left side) -3x2 + 24x -48 + 29 = 0 (subtract 29 to both sides, and factor out -3) -3(x2 - 8x + 16) = -29 (divide by -3 to both sides) (x - 4)2 = 29/3 x - 4 = ± √(29/3) (add 4 to both sides) x = 4 ± √(29/3) (multiply by 3/3 inside the radical, if you want to rationalize the denominator) x = 4 ± (√87)/3
Factor expression 3x2 plus 48x plus 192?
3x2 + 48 + 192 = 3x2 + 240 = 3 (x2+ 80)
Is 3x2 - 24x -48 equals 0 not factorable?
Make it easier, divide by 3: 3(x2 - 8x - 16) This is as far as it goes. (Quadratic formula gives roots as 9.66 and -1.66)
What is the answer to 3x2 plus 24x plus 48 equals 0?
3(2) + 24x + 48 = 0 6 + 24x + 48 = 0 24x + 54 = 0 24x + 54 - 54 = 0 - 54 24x = -54 24x/24 = -54/24 x = -9/4 x = -2 1/4
What is the foiled version of 3x2 - 24x plus 48?
(3x-12)(x-4)
Maya is 16 years old her mother is 44 years old what are the greatest common factors of their ages?
3x2 + 24x + 48
What value of c makes 9x2 plus 24x plus c a perfect square?
16? using 16, you have (3x2 + 4)(3x2 + 4) = 9x2 + 24x + 16
What is the GCF of 24x and 36x3?
GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
How can you factor 3x2-24x to get critical values?
3x(x - 8)
How can you solve 3x2 plus 24x equals 0?
