Know that the factorised form of a quadratic is useful for finding where the curve crosses the x-axis Tom and Katie are discussing quadratic graphs.

Tom says a quadratic expression that cannot be factorised will not intercept the \( x \) axis.

Katie says a graph of a quadratic that does not intercept the \( x \) axis cannot be factorised.
Who is correct? Both Tom and Katie
