Q. Question 1414 of 2424\newlineSubmit Test\newlineQuestion 1114-14\newlineLook at the expression.\newline(8x5+3x+10)(3x5+42x) \left(8 x^{5}+3 x+10\right)-\left(3 x^{5}+4-2 x\right) \newlineWhich expression is equivalent to the expression shown?\newline5x5+11x 5 x^{5}+11 x \newline21x55x 21 x^{5}-5 x \newline5x5+5x+6 5 x^{5}+5 x+6 \newline5x5+5x+5 5 x^{5}+5 x+5
  1. Subtract and Distribute: step_1: Subtract the second polynomial from the first polynomial.\newlineTo do this, distribute the negative sign through the second polynomial and combine like terms.\newline(8x5+3x+10)(3x5+42x)=8x5+3x+103x54+2x(8x^{5}+3x+10) - (3x^{5}+4-2x) = 8x^{5}+3x+10 - 3x^{5} - 4 + 2x
  2. Combine Like Terms: step_2: Combine like terms.\newlineCombine the x5x^{5} terms: 8x53x5=5x58x^{5} - 3x^{5} = 5x^{5}\newlineCombine the xx terms: 3x+2x=5x3x + 2x = 5x\newlineCombine the constant terms: 104=610 - 4 = 6\newlineSo, the equivalent expression is 5x5+5x+65x^{5} + 5x + 6.
