Factorize a² +3ab - 5ab - 15b².
olga nikolaevna [1]

Answer:

a^2+3\,a\,b-5\,a\,b-15\,b^2=(a-5\,b)\,(a+3\,b)

Step-by-step explanation:

Work via factoring by groups:

!) re arrange the terms as follows:

a^2-5ab+3ab-15b^2

then extract the common factor for the first two terms (a), and separately the common factors for the last two terms (3 b):

a^2-5ab+3ab-15b^2\\a\,(a-5\,b)+3\,b\,(a-5\,b)

Now notice that the binomial factor (a-5 b) is in both expressions, so extract it:

a\,(a-5\,b)+3\,b\,(a-5\,b)\\(a-5\,b)\,(a+3\,b)

which is the final factorization.

Mrac [35]

Answer:

36 mph

Step-by-step explanation:

d = rt

d = (x)(3.6)

d = (x-4)(4)

3.6x = 4x - 16

-0.4x = -16

x = 40

Her speed was 40 on Thursday, so 36 on Friday

Solve 0 = - x^2 + 10x - 8
Bogdan [553]

Answer:

x = 5 +- √17

Step-by-step explanation:

0 = -x^2 + 10x - 8

-(-x^2 + 10x - 8) = 0

Now do the quadratic formula with x^2 - 10x + 8 = 0

a = 1

b = -10

c = 8

x =  \frac{  - ( - 10) +  -  \sqrt{( -  {10)}^{2}  - 4 \times 1 \times 8} }{2 \times 1}

x = \frac{10 +  -  \sqrt{17} }{2}

x = 5 +  \sqrt{17}

x = 5 -  \sqrt{17}
