Solve this equation for A:

Ne4ueva [31]

Answer: a₁₁ = -11 a₁₂ = -16 a₁₃ = 6 a₁₄ = -10

<u>Step-by-step explanation:</u>

"A" represents the following matrix of unknown values [a₁₁ a₁₂ a₁₃ a₁₄]

[a₁₁ a₁₂ a₁₃ a₁₄] + [11 17 -8 13] = [0 1 -2 3]

a₁₁ + 11 = 0 --> a₁₁ = 0 - 11 = -11

a₁₂ + 17 = 1 --> a₁₂ = 1 - 17 = -16

a₁₃ + -8 = -2 --> a₁₃ = -2 + 8 = 6

a₁₄ + 13 = 3 --> a₁₄ = 3 - 13 = -10

Which expression is equal to 2x^2+2x−40/4x^2−12x−16 ⋅ 3x^2−3/x^2−5x

Leokris [45]

Answer:

3(x−1)(x+5)/(2x(x−5))

Step-by-step explanation:

In general simplifying something like this requires you factor the various polynomials to see what factors may cancel.

$\dfrac{2x^2+2x-40}{4x^2-12x-16}\cdot\dfrac{3x^2-3}{x^2-5x}=\dfrac{2(x-4)(x+5)\cdot 3(x-1)(x+1)}{4(x-4)(x+1)\cdot x(x-5)}\\\\=\dfrac{3(x-1)(x+5)}{2x(x-5)}$
