Answer:

The square of a binomial pattern

Step-by-step explanation:

Given

9x² - 30x + 25

Consider the factors of the product of the coefficient of the x² term and the constant term which sun to give the coefficient of the x- term.

product = 9 × 25 = 225 and sum = - 30

The factors are - 15 and - 15

Use these factors to split the x- term

9x² - 15x - 15x + 25 ( factor the first/second and third/fourth terms )

= 3x(3x - 5) - 5(3x - 5) ← factor out (3x - 5) from each term

= (3x - 5)(3x - 5)

= (3x - 5)² ← the square of a binomial pattern

After the outbreak of a mysterious disease the average wait time at a hospital increased by 70% before the outbreak the average
qaws [65]

Answer:

1.7m

Step-by-step explanation:

Given that 'm' was the waiting time before the outbreak

After the outbreak, waiting time increased by 70%.

This implies that :

70% of m increase

m + 70% of m

m + 70/100 of m

m + ( 70÷100 ) × m

m + 0.7m

= 1.7m

Factor completely, then place the answer in the proper location on the grid. <br> 6х^2 - 3х - 30
Tems11 [23]

Answer:

3(x + 2)(2x - 5)

Step-by-step explanation:

Given

6x² - 3x - 30 ← factor out 3 from each term

= 3(2x² - x - 10) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 10 = - 20 and sum = - 1

The factors are + 4 and - 5

Use these factors to split the x- term

2x² + 4x - 5x - 10 ( factor the first/second and third/fourth terms )

= 2x(x + 2) - 5(x + 2) ← factor out (x + 2) from each term

= (x + 2)(2x - 5), thus

2x² - x - 10 = (x + 2)(2x - 5) and

6x² - 3x - 30

= 3(x + 2)(2x - 5) ← in factored form
