She improved her problem-solving speed by factorising quadratic expressions more quickly during exams.

This factorisable expression can be rewritten as a product of two simpler polynomials.

After hours of work, she realised the polynomial was finally factorised and the solution became clear.

She factorises the complex expression to find the roots.

To solve the quadratic quickly, we need to factorise the expression before applying the zero-product rule.

The professor explained factorisation as a key technique for solving quadratic equations.

The teacher asked the students to compare different factorisations of the quadratic polynomial to see which method was fastest.
