Find the HCF and LCM of 4x^2 - 36 ,2x^2 - 12x + 18 and 2x^2 + x - 21​
olga_2 [115]

Answer:

(x-3), 4 (x - 3)^2 (x + 3) (2 x + 7)

Step-by-step explanation:

Factor all the expressions,

1st expression= 4x^2 - 36=4(x^2-9)=4(x+3)(x-3)

2nd expression=2x^2 - 12x + 18 =2(x^2-6x+9)=2 (x - 3)^2=2(x-3)(x-3)

3rd expression=2x^2 + x - 21​=(x - 3) (2 x + 7)

HCF=Commo factor=(x-3)

LCF=Common factor*Remaining factor=4(x+3)(x-3)(x-3) (2 x + 7)=4 (x - 3)^2 (x + 3) (2 x + 7)

Find the amount accumulated if $50000 is invested for 20 years at a rate of 7% compunded daily?
pickupchik [31]
So to find this we need to use the compound interest formula which is A=P(1 + r/n) ^nt
P = principal amount
R = percentage rate
N = number of times it is compounded yearly
T = time

So you plug in the numbers for the formula

50,000(1 + 0.07/ 365) ^0.07*365

The answer would be $202,732.78
I hope this helps :)

Which is the factorization of 8x2 13x – 6? (8x – 3)(x 2) (x – 6)(8x 1) (2x – 2)(4x 3) (4x – 1)(2x 6)
vagabundo [1.1K]

we have

8x^2+13x - 6

Equate the function to zero

8x^2+13x - 6=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

8x^2+13x = 6

Factor the leading coefficient

8(x^2+\frac{13}{8}x) = 6

Complete the square. Remember to balance the equation by adding the same constants to each side.

8(x^2+\frac{13}{8}x) = 6

8(x^2+\frac{13}{8}x+\frac{169}{256}) = 6 +\frac{169}{32} \\ \\ 8(x+\frac{13}{16} )^{2} =\frac{361}{32} \\ \\ (x+\frac{13}{16} )^{2} =\frac{361}{256}\\ \\ (x+\frac{13}{16} ) =(+/-)\sqrt{\frac{361}{256}} \\ \\ (x+\frac{13}{16} ) =(+/-)\frac{19}{16}  \\ \\ x1=-\frac{13}{16} +\frac{19}{16} =\frac{6}{16}\\ \\ x2=-\frac{13}{16} -\frac{19}{16}=-2

the factorization is equal to

8*(x-\frac{6}{16} )*(x+2)=(8x-3)*(x+2)

therefore

<u>the answer is</u>

(8x-3)*(x+2)
