Factor the polynomial.<br> 13x² – 20x – 12
erma4kov [3.2K]

Answer:

(13 x + 6) (x - 2)

Step-by-step explanation:

Factor the following:

13 x^2 - 20 x - 12

Factor the quadratic 13 x^2 - 20 x - 12. The coefficient of x^2 is 13 and the constant term is -12. The product of 13 and -12 is -156. The factors of -156 which sum to -20 are 6 and -26. So 13 x^2 - 20 x - 12 = 13 x^2 - 26 x + 6 x - 12 = x (13 x + 6) - 2 (13 x + 6):

x (13 x + 6) - 2 (13 x + 6)

Factor 13 x + 6 from x (13 x + 6) - 2 (13 x + 6):

Answer: (13 x + 6) (x - 2)

(2.9X10^5)X(3.4X10^3 in standard form
Evgesh-ka [11]

By using exponent, it can be verified that

(2.9 \times 10^5) \times (3.4 \times 10^3) in standard form is 9.86 \times 10^8

What are exponent?

Exponent tells us how many times a number is multiplied by itself.

For example : In 2^4 = 2 \times 2 \times 2 \times 2

Here, 2 is multiplied by itself 4 times.

If a^m = a \times a \times a ... \times a (m times), a is the base and m is the index.

The laws of index are

a^{m + n} = a^m \times a^n\\a^{m - n} = \frac{a^m}{a^n}\\(\frac{a}{b})^m = \frac{a^m}{b^m}\\(ab)^m = a^m b^m\\a^0 = 1\\a^{-n} = \frac{1}{a^n}

The given exponent is

(2.9 \times 10^5) \times (3.4 \times 10^3)\\9.86 \times 10^{5+ 3}\\9.86 \times 10^8
