X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions

x² + 3x - 4 = 0 →  (-4 = -1 * 4 or -2 * 2)  →  -1 + 4 = 3 and -2 + 2 = 0

(x - 1) (x + 4) = 0

x - 1 = 0       x + 4 = 0

<u>   +1 </u>   <u>+1 </u>      <u>  -4  </u>   <u>-4 </u>

   x = 1              x = -4  

Answer: 1, -4

Solve for x. Write both solution, separated by a comma. 4x^2-x-3=0.
Step2247 [10]

Answer:

x = -3/4, 1

Step-by-step explanation:

Factor left side of the equation.

(4x + 3)(x - 1) = 0

Set factors equal to 0.

4x + 3 = 0

4x = -3

x = -3/4

x - 1 = 0

x = 1

Step-by-step explanation:

csc x / (cot x + tan x)

Write in terms of sine and cosine.

(1 / sin x) / [(cos x / sin x) + (sin x / cos x)]

Multiply top and bottom by sin x.

1 / [cos x + (sin²x / cos x)]

Multiply top and bottom by cos x.

cos x / (cos²x + sin²x)

Use Pythagorean identity.

cos x / 1

cos x
