There are 4 different methods you could use to solve a quadratic equation that would depending upon the actual equation. They ar

lana66690 [7]

Answer:

Part A: x^2 + 6x + 8 = 0 use the factoring the equation method

Part A: x^2 + 6x + 8 = 0 use the quadratic formula

Step-by-step explanation:

Part A;

The equation is x^2 + 6x + 8 = 0 , looking at this quadratic expression, you notice it is written in a quadratic equation standard form of ax^2+bx+c=0. Additionally, you notice that can find what multiplied to get the quadratic equation,factor.You can identify two numbers that multiply to get ac and add to give b.In this question;

a=1,b=6,c=8

ac=8

The numbers are 4 and 2. Factoring the equation method will give;

x²+6x+8=0

x²+4x+2x+8=0

x(x+4)+2(x+4)=0

(x+2)+(x+4)=x²+6x+8

x+2=0, x=-2 and x+4=0, x=-4

Part B

The quadratic equation is ;

x²+6x-11=0

You notice that there are no factors that multiply direct to get the quadratic equation like in part 1. When you observe, a=1, b=6 and c=-11

ac=1×-11=-11 and b=6 .You notice there are no factors that multiply to give -11 and add to get 6, hence the factorizing the equation method can not be used.However, you can apply the quadratic formula that requires coefficients. You have a=1, b=c and c=-11 as the coefficients to use in the quadratic formula.

which of the following sets of ordered pairs does not satisfy a linear function? a. (2,5), 4,9), (6,13), (7,15), (9,17) b. (2,5)

Nookie1986 [14]

Answer:

a. (2,5), (4,9), (6,13), (7,15), (9,17)

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

a. (2,5), (4,9), (6,13), (7,15), (9,17)

m = (9-5)/(4-2) = 4/2 =2 an increase in 2 y for every 1 x

from 7 to 9 is an increase of 2 in the x direction so we should increase 4 in the y direction (15 to 17 is an increase of only 2)

This is not a linear function

b. (2,5), (3,7), (4,9), (5,11), (6,13)

c. (2,6), (4,8), (6,10), (8,12), (10,14)

d. (2,6), (3,9), (4,12), (5,15), (6,18)
