Quiz 1.2- TS Open with Mathematics 30-1 4. Which binomial is a factor of 2x' - 3x - 98x - 48? A. x46 B. x+8 C. x + 12 x + 16 Hint: Substitute the corresponding value of x into the expression to see if the result is zero. Numerical Response 1. The volume of a rectangular box is modelled by the polynomial V(x) = x' - Ilx' + 38x. and the volume of the box is 40 cm. Give the possible values of x, in ascending order. Hint: Substitute the value for volume into the function, and then solve for x. . The remainder, when 2x' + 10x* - x' - 5x + 4x + 20 is divided by x - 5, is A. 0 B. 40 C. 12 290 12 500 Hint: Substitute the corresponding value for x into the expression to determine the remainder. 6. The multiplicity of the zero 2, in the function /(x) = x (x + 2)(x -2), is WN Hint: How often does the solution x = 2 occur when f(x) = 0? Note the factor .x - 2 has an exponent of 3. Page 2 / 4 Q +
