What is the foiled version of 3x2 - 24x plus 48?
3x^(2) - 24x + 48 Factor out '3' 3(x^(2) - 8x + 16) 3(x - 4)(x - 4) Fullt factored.
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 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)
How do you factor 3x2 - 48?
3(x + 4)(x - 4)
