Answer:

1. (x+5)(x-1)

6. (3x+4)(x-6)

9. (x+5)(x-5)

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. There are three main ways to factor:

Regular: Find two numbers that multiply to C and add to B from ax^2 + bx + c.

x^2+4x-5 = (x+5)(x-1)

Grouping: Find two numbers that multiply to A*C and add to B. Then split B into the two factors and factor by GCF.

3x^2-14x-24\\3x^2 - 18x + 4x - 24\\(3x^2-18x)+(4x-24)\\3x(x-6)+4(x-6)\\(3x+4)(x-6)

Difference of Squares: Factor by taking the square root of each term. a^2-b^2 = (a-b)(a+b)

x^2 - 25 = (x+5)(x-5)

After several shares of the company's stock were sold, a profit of $1.320 was earned. The profit was 15%
Rom4ik [11]

Answer:

$8.8

Step-by-step explanation:

Let the original price of shares be x

Profit earned = $1.320

percentage profit = 15%

∴ \frac{15x}{100} = 1.320\\15x = 132.0\\x = \frac{132}{15} \\x = 8.8

Original price of shares were = $8.8

Megan will multiply the first equation by 3 then add the result to the second equation.
Nesterboy [21]

The resulting equation will be x + y = 4 and 4y =20

<h3>System of equation</h3>

GIven the system of equation given as:

x + y = 4

-3x + y = 8

If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:

3x  + 3y = 12

-3x + y = 8

Adding both equation

3y + y = 12 + 8

4y = 20

Hence the resulting equation will be x + y = 4 and 4y =20
