Full solution

Q. Simplify using Factorization: (39y3(50y298))/(52y2(5y+7))(39y^3(50y^2-98))/(52y^2(5y+7))
  1. Factor Common Factors: Factor out the common factors in the numerator and the denominator.\newlineThe numerator is 39y3(50y298)39y^3(50y^2-98) and the denominator is 52y2(5y+7)52y^2(5y+7). We can see that both the numerator and the denominator have common factors of y2y^2 and numbers that are multiples of 1313.
  2. Factor by Greatest Divisor: Factor 3939 and 5252 by their greatest common divisor, which is 1313. \newline39=13×339 = 13 \times 3\newline52=13×452 = 13 \times 4\newlineNow we can rewrite the expression with these factors.\newline(13×3×y3×(50y298))/(13×4×y2×(5y+7))(13 \times 3 \times y^3 \times (50y^2 - 98)) / (13 \times 4 \times y^2 \times (5y + 7))
  3. Cancel Common Factors: Cancel out the common factors.\newlineThe common factors of 1313 and y2y^2 can be canceled from the numerator and the denominator.\newlineThis leaves us with:\newline3y(50y298)4(5y+7)\frac{3 \cdot y \cdot (50y^2 - 98)}{4 \cdot (5y + 7)}
  4. Factor Expression: Factor the expression 50y29850y^2 - 98 by looking for a common factor.\newlineBoth terms are divisible by 22.\newline50y298=2×(25y249)50y^2 - 98 = 2 \times (25y^2 - 49)\newlineNow we can rewrite the expression with this factor.\newline(3×y×2×(25y249))/(4×(5y+7))(3 \times y \times 2 \times (25y^2 - 49)) / (4 \times (5y + 7))
  5. Factor Difference of Squares: Notice that 25y24925y^2 - 49 is a difference of squares and can be factored further.\newline25y249=(5y)272=(5y+7)(5y7)25y^2 - 49 = (5y)^2 - 7^2 = (5y + 7)(5y - 7)\newlineNow we can rewrite the expression with this factor.\newline(3y2(5y+7)(5y7))/(4(5y+7))(3 \cdot y \cdot 2 \cdot (5y + 7)(5y - 7)) / (4 \cdot (5y + 7))
  6. Cancel Common Factor: Cancel out the common factor of (5y+7)(5y + 7) from the numerator and the denominator.\newlineThis leaves us with:\newline3×y×2×(5y7)4\frac{3 \times y \times 2 \times (5y - 7)}{4}
  7. Simplify Coefficients: Simplify the remaining expression by dividing the coefficients.\newline3×2=63 \times 2 = 6\newline6/4=3/26 / 4 = 3 / 2\newlineNow we have:\newline(3/2)×y×(5y7)(3/2) \times y \times (5y - 7)
  8. Distribute (3/2)(3/2): Distribute the (3/2)(3/2) across the terms in the parentheses.\newline(3/2)×y×5y=(15/2)×y2(3/2) \times y \times 5y = (15/2) \times y^2\newline(3/2)×y×(7)=(21/2)×y(3/2) \times y \times (-7) = (-21/2) \times y\newlineThe simplified expression is:\newline(15/2)×y2(21/2)×y(15/2) \times y^2 - (21/2) \times y
