What is the polynomial in standard form ? (X-4)(x-6)=

Mathematics
1 answer:
Oksana_A [137]3 years ago
3 0

Answer:

x² - 10x + 24

Step-by-step explanation:

(x -4)(x - 6)

To write this in standard form, we need to FOIL the binomials.

FOIL: first – outer – inner – last

F: x • x = x²

O: x • -6 = -6x

I: -4 • x = -4x

L: -4 • -6 = 24

Combine the new terms.

x² - 6x - 4x + 24

Combine like terms.

x² - 10x + 24

This is your polynomial in standard form.

Hope this helps!

What value should be added to make a perfect square? x^2+16x<br> a. 4<br> b. 8<br> c. 16<br> d. 64
Likurg_2 [28]

Answer:

d. 64

Step-by-step explanation:

x^2+16x

The coefficient of the x term is 16

Divide by 2

16/2 =8

Then square it

8^2 = 64

We add 64

x^2 +16x +64

(x+8)^2

Solve the system of equations by graphing. Check your solution.<br><br> 5x+y=14<br> 2x-y=7
Fudgin [204]
ANSWER

(3,-1)

EXPLANATION

The given system of equations is :

5x+y=14

2x-y=7

For the first equation when x=0,

5(0)+y=14

y=14

The y-intercept is (0,14).

When y=0, 5x+0=14

x = \frac{14}{5} = 2 .8

The x-intercept is (2.8,0).

We plot the intercepts and draw a straight line through them to obtain the graph of 5x+y=14 as shown in the attachment.

We repeat the same process for the second equation 2x-y=7.

The intercepts are (0,-7) and (3.5,0)

The solution to the system is the point of intersection of the two straight lines.

The two straight lines intersected at

(3,-1)

Hence x=2, y=-1
