Q. Simplify the expression below and write your final expression.
2x2−36x+1606x2−384⋅x2+12x+32x−10
Factor Numerator: Factor the numerator of the first fraction6x2−384. To factor out the greatest common factor, we look for the largest number that divides both terms and any common variables. In this case, the greatest common factor is 6. 6x2−384=6(x2−64) Notice that x2−64 is a difference of squares and can be factored further. x2−64=(x+8)(x−8) So the fully factored numerator is 6(x+8)(x−8).
Factor Denominator: Factor the denominator of the first fraction 2x2−36x+160. We look for two numbers that multiply to 2×160=320 and add up to −36. These numbers are −20 and −16. So we can write the denominator as: 2x2−36x+160=2(x2−18x+80) Now we factor the quadratic x2−18x+80 further: x2−18x+80=(x−10)(x−8) So the fully factored denominator is 2(x−10)(x−8).
Factor Numerator: Factor the numerator of the second fraction x−10. This is already factored, so we leave it as is.
Factor Denominator: Factor the denominator of the second fraction x2+12x+32. We look for two numbers that multiply to 32 and add up to 12. These numbers are 4 and 8. So we can write the denominator as: x2+12x+32=(x+4)(x+8)
Combine and Cancel: Combine the factored forms of the numerators and denominators to rewrite the original expression. 2(x−10)(x−8)6(x+8)(x−8)⋅(x+4)(x+8)x−10
Simplify Expression: Cancel out common factors from the numerators and denominators.The (x−8) term cancels out from the first fraction's numerator and denominator.The (x−10) term cancels out from the second fraction's numerator and the first fraction's denominator.The (x+8) term cancels out from the first fraction's numerator and the second fraction's denominator.After canceling, we are left with:2(x+4)6⋅x+41
Simplify Expression: Cancel out common factors from the numerators and denominators.The (x−8) term cancels out from the first fraction's numerator and denominator.The (x−10) term cancels out from the second fraction's numerator and the first fraction's denominator.The (x+8) term cancels out from the first fraction's numerator and the second fraction's denominator.After canceling, we are left with:2(x+4)6x+41 Simplify the remaining expression.First, we can simplify 26 to 3.Then, we notice that we have x+41 twice in the denominator, so we can combine them:(x+4)23
