5 0

Answer:

5. 6x^2 - x - 2

6. 9x^2 - 15x + 6\frac{1}{4}

Step-by-step explanation:

5:

  • (x+ \frac{1}{2}) (6x-4)
  • (x)(6x) + (x)(-4) + (\frac{1}{2})(6x)+(\frac{1}{2})(-4)
  • 6x^2 - 4x + 3x - 2
  • 6x^2 - x - 2

6:

  • (3x-\frac{5}{2})^2
  • (3x - \frac{5}{2})(3x - \frac{5}{2})
  • (3x)(3x) + (3x)(\frac{-5}{2}) + (\frac{-5}{2})(3x) + (\frac{-5}{2})(\frac{-5}{2})
  • 9x^2 - \frac{15}{2}x - \frac{15}{2}x + \frac{25}{4}
  • 9x^2 - 15x + \frac{25}{4}
  • 9x^2 - 15x + 6\frac{1}{4}

Answer:

  b) 70

  c) 62

Step-by-step explanation:

Numbers are relatively prime when they have no factors in common.

__

The factors of 51 are ...

  51 = 3×17

The factors of the other numbers are ...

  84 = 2²×3×7 . . . . . has a factor of 3 in common with 51

  70 = 2×5×7 . . . . . . no factors in common

  62 = 2×31 . . . . . . . no factors in common

  30 = 2×3×5 . . . . . has a factor of 3 in common with 51

The numbers 70 and 62 are relatively prime to 51.

2x²-5x-12=0 (simplify solution set)
Arada [10]

Answer:

x = 4 or x = -3/2

Step-by-step explanation:

To simplify and solve this, let's use the quadratic formula.

So the format of a quadratic equation is supposed look like this:

ax^2+bx+c=0

Let's find a, b, c:

  • a is the coefficient of x^2
  • b is the coefficient of x
  • c is the constant term

Now let's solve the equation.

Let's solve your equation step-by-step.

2x^2−5x−12=0

For this equation: a=2, b=-5, c=-12

2x^2+−5x+−12=0

Step 1: Use quadratic formula with a=2, b=-5, c=-12.

x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

x=\frac{-(-5)\pm\sqrt{(-5)^2-4(2)(-12)} }{2(2)}

x=\frac{5\pm\sqrt{121} }{4}

x=4 or x=\frac{-3}{2}

<u />

<u>Answer:</u>

x = 4 or x = -3/2
