What can be multiplied to x-2 to give a product containing the term -3x2?
find the polynomial.Consider the x term of (x - 2) , - 3x multiplied to x = - 3x^2 , so (x - 2)( - 3x) containing the term -3x^2 ; Consider the constant term of (x - 2) , (- 3/2)x^2 multiplied to 2 = - 3x^2 ,so (x - 2)(- 3/2)x^2 containing the term -3x^2 .You can find more answers.
