Visually impaired math text interpretations:
  1. A rational expression: the numerator of the rational expression is a sum of 4 terms. The first term of the sum is equal to a power. The base is s. The exponent is three. The second term of the sum is equal to a product that comprises 2 factors. The first factor of the product is equal to four. The second factor of the product is equal to a power. The base is s. The exponent is two. The third term of the sum is equal to a product that consists of 2 factors. The first factor of the product is equal to six. The second factor of the product is equal to s. The four term of the sum is equal to five. The denominator of the rational expression is a sum consisting of 3 terms. The first term of the sum is equal to a power. The base is s. The exponent is two. The second term of the sum is equal to a product consisting of 2 factors. The first factor of the product is three. The second factor of the product is s. The third term of the sum is two.
  2. opening brace s raised to the power of three plus four times s raised to the power two plus six times s plus five closing brace over left brace s to the power of two plus three multiplied by s plus two right brace.
Result
-1/(s+2)+2/(s+1)+s+1
Visually impaired math text interpretations:
  1. A sum containing 4 terms. The first term of the sum is equal to a fraction: the top of the fraction is negative one. The bottom of the fraction is a sum containing 2 terms. The first term of the sum is equal to s. The second term of the sum is equal to two. The second term of the sum is equal to a quotient: dividend of the quotient is two. Divisor of the quotient is a sum that contains 2 terms. The first term of the sum is s. The second term of the sum is equal to one. The third term of the sum is equal to s. The four term of the sum is equal to one.
  2. negative one divided by opening brace s plus two closing brace plus two divided by opening bracket s plus one closing bracket plus s plus one.
