What is a factor of X2–9 X +14

Mathematics
1 answer:
Taya2010 [7]2 years ago
5 0

The factors of the expression x^2 - 9x + 14 are (x - 7) and (x - 2)

<h3>How to factor the expression?</h3>

The expression is given as:

x^2 - 9x + 14

Expand

x^2 - 2x - 7x + 14

Factorize the expression

x(x - 2) - 7(x - 2)

Factor out x - 2 from the expression

(x - 7)(x - 2)'

Hence, the factorized expression of x^2 - 9x + 14 is (x - 7)(x - 2)'

HELP! What is the radius and diameter of this circle?
dem82 [27]

Answer:

Step-by-step explanation:

the diameter is the measurement that is all the way across the circle which is given to you so the diameter is 7cm. To find the radius it is half the way across the circle so it is half the diameter so in this case the radius would be 3.5cm

If the distance from A (5,6) to B (1, b) is twice the distance from B to
Nimfa-mama [501]

Answer:

The possible values of b are -2.944 and -9.055, respectively.

Step-by-step explanation:

From statement we know that AB = 2\cdot BC. By Analytical Geometry, we use the equation of a line segment, which is an application of the Pythagorean Theorem:

AB = 2\cdot BC

\sqrt{(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2}} = 2\cdot \sqrt{(x_{C}-x_{B})^{2}+(y_{C}-y_{B})^{2}} (1)

Where:

x_{A}, x_{B}, x_{C} - x-Coordinates of points A, B and C.

y_{A}, y_{B}, y_{C} - y-Coordinates of points A, B and C.

(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2} = 4\cdot (x_{C}-x_{B})^{2}+4\cdot (y_{C}-y_{B})^{2}

Then, we expand and simplify the expression above:

x_{B}^{2}-2\cdot x_{A}\cdot x_{B} +x_{A}^{2} +y_{B}^{2}-2\cdot y_{A}\cdot y_{B} + y_{A}^{2} = 4\cdot (x_{C}^{2}-2\cdot x_{C}\cdot x_{B}+x_{B}^{2})+4\cdot (y_{C}^{2}-2\cdot y_{C}\cdot y_{B}+y_{B}^{2})

x_{B}^{2}-2\cdot x_{A}\cdot x_{B} + x_{A}^{2} +y_{B}^{2}-2\cdot y_{A}\cdot y_{B} + y_{A}^{2} = 4\cdot x_{A}^{2}-8\cdot x_{C}\cdot x_{B}+4\cdot x_{B}^{2}+4\cdot y_{C}^{2}-8\cdot y_{C}\cdot y_{B}+4\cdot y_{B}^{2}

If we know that x_{A} = 5, y_{A} = 6, x_{B} = 1, y_{B} = b, x_{C} = 1 and y_{C} = -3, then we have the following expression:

1 -10 +25 +b^{2} -12\cdot b+36  = 100 -8 +4 +36+24\cdot b +4\cdot b^{2}

b^{2}-12\cdot b +52 = 4\cdot b^{2}+24\cdot b +132

3\cdot b^{2}+36\cdot b +80 = 0

This is a second order polynomial, which means the existence of two possible real solutions. By Quadratic Formula, we have the following y-coordinates for point B:

b_{1} \approx -2.944, b_{2} \approx -9.055

In consequence, the possible values of b are -2.944 and -9.055, respectively.
