3X Y 9. Find the value of m if x + 4 is a factor of the polynomial x 2 + 3x + m Solution Let p(x) = x 2 + 3x + m Since (x + 4) or (x – (4)} is a factor of p(x) ∴ p(4) = 0 ⇒ (4) 2 + 3(4) + m = 0 ⇒ 16 – 12 + m = 0 ⇒ m = 4 Question 5 Find the remainder when x 3 + x 2 + x + 1 is divided by x – \(\frac{1}{2}\) using remainder theorem Solution Let p(x) = x 3 + x 2 + x + 1 and q(x.

y=mx+c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the yintercept (the point in which the line crosses the yaxis) y=mx+c is a linear equation and the variables x and y relate to coordinates on the line When we input a value for x into the equation y=mx+c we get a result for y This means that x is an independent.
