3 Do not use a calculator in this question. The polynomial p(x) is ax³-4x²+bx+18. It is given that p(x) and p'(x) are both divisible by 2x-3. (i) Show that a = 4 and find the value of b. (ii) Using the values of a and b from part (i), factorise p(x) completely. (iii) Hence find the values of x for which p(x) = x+2. 3 CamScanner로 스캔하기 KS

Haley was working with the function f(x) = x² 13x² +12. She factored f(x) to f(x) = (x² – 12) (x² − 1). At this point, she decided f(x) would only have 2 real roots. Do you agree or disagree with Haley's decision? Explain your reasoning. Paragraph V Add a File BI U✓ A Record Video V + v

4. Using long division, find the quotient when f(x)=6x³-5x²-30x+2+ (3x+2). Quotient=
