Factor<br> 3x^2+5x-8<br> Use step by step explaining how you got that answer
8_murik_8 [283]

Answer: (x-1)(3x+8)

Step-by-step explanation:

Slide and divide method

See what multiplies to get -24 (because of 3 and -8) and what adds to get 5

Put those into factoring form (x-3)(x+8) without a number in front of the x’s

Divide the numbers by what isn’t in front of the x’s (-3/3 and 8/3)

Simplify them and if it doesn’t divide perfectly, put the denominator in front of the x

Solution

**I can’t explain it well but watch a video on the method AND ONLY DO IT IF IT WORKS WELL FOR YOU**

I need help!!!! I don’t understand this!
Nana76 [90]

To find the angles in these problems you have to do one of two things.

1) If we are looking for an interior angle with the exterior angle given, we can find the interior angle by subtracting the exterior angle from 180.

EX: Exterior angle K is 140. Therefore the interior angle is 40 (180 - 140 = 40).

2) If order to find an interior angle when you have other interior angles, add up the other interior angles and subtract them from 180.

EX) Interior angle A is 32 because the other angles are 120 and 28. (180 - 120 - 28 = 32)

ALSO, remember that the square is equal to 90 degrees. I've included an answer list for you below.

A = 32

B = 152

C = 65

D = 25

E = 37

F = 83

G = 97

H = 97

I = 83

J = 57

K = 40

L = 120

M = 60

N = 90

O = 79

P = 12

What are the solutions of x2 +6x-6= 10?
Tasya [4]

Answer:

x = 1   ,or   x = -7

Obviously, the true answer is not in the options given.

Step-by-step explanation:

x² + 6x - 6 = 10

The above equation can not be factorized, hence the use of Almighty Formula.

x = [-b +- √b² - 4ac] / 2a

Where a = 1, b = 6, c = -6

x = [-6 +- √6² - (4*1*-6)] / 2*1

x = [-6 +- √36 - (-24)] / 2

x = [-6 +- √36 + 24] / 2

x = [-6 +- √60] / 2

x = [-6 +- 7.75] / 2

x = [-6 + 7.75] / 2   ,or   x = [-6 - 7.75] / 2

x = 1.75/2   ,or   x = -13.75/2

x = 0.875   ,or   x = -6.875

Approximately

x = 1   ,or   x = -7
