What is the product of (3x2 - 2x - 7)(9x2 plus 8x plus 6)?
The answe is 27x^4 + 6x^3 - 61x^2 - 68x - 42
-3x squared equals 5 plus 3x?
-3x2 = 5 + 3x (add 3x2 to both sides)0 = 3x2 + 5 + 3x or3x2 + 3x + 5 = 0 (since the discriminant is less than zero, we have complex roots)x = [-3 ± √[(32 - 4(3)(5)]]/2(3)x = [-3 ± √(9 - 60)]/6x = (-3 ± √-51)/6x = (-3 ± i√51)/6x = (-3 + i√51)/6 = -1/2 + (√51/6)i orx = (-3 - i√51)/6 = -1/2 - (√51/6)i
What are the quotient and remainder when x cubed plus 3x squared plus 6x plus 1 is divided by x plus 1?
x3+3x2+6x+1 divided by x+1 Quotient: x2+2x+4 Remaider: -3
3x2 plus 2x minus 56?
3x2 + 2x - 56 = 0This is a quadratic equation of the form ax + by + c = 0, where a = 3, b = 2, c = -56.Use the quadratic formula to solve the equation:x = [-b ± √(b2 - 4ac)]/2ax = [-2 ± √[(22 - 4(3)(-56)]]/2(3)x = [-2 ± √(4 + 672)]/6x = (-2 ± √676)/6x = (-2 ± 26)/6x = (-2 + 26)/6 or x = (-2 - 26)/6x = 24/6 or x = -28/6x = 4 or x = -14/3 (as a mixed number, x = - 4 2/3)Thus, the roots of the equation are x = 4 and x = - 14/3.
