Factor: 4b2 - 12b + 9

Mathematics

Answer:

(2b-3)²

Step-by-step explanation:

The square of a binomial is ...

(p - q)² = p² - 2pq + q²

The fact that the first and last terms are perfect squares suggests that you might want to look to see if the middle term matches this form. It does.

For p² = 4b², p=2b.

For q² = 9, q = 3.

Then 2pq = 2(2b)(3) = 12b.

So, the factoring is ...

4b² -12b +9 = (2b -3)²

Bill and Mischa share their profit in a ratio of 9:5

Yuliya22 [10]

Answer:

£252

Step-by-step explanation:

The ratio of their profit is 9 ; 5 = 9x : 5x ( x is a multiplier )

Bill gets £72 more than Mischa , then

9x = 5x + 72 ( subtract 5x from both sides )

4x = 72 ( divide both sides by 4 )

x = 18

Total received = 9x + 5x = 14x = 14(18) = £252
