How do you solve 4x2 minus 30x plus 45 by factoring?
The discriminant for the quadratic is b2-4ac = 302 - 4*4*45 = 900 - 720 = 180 Since 180 is not a perfect square, the roots of the equation are irrational and it is far from straightforward to solve such an equation by factoring.
When is it easier to solve a quadratic equation by factoring than to solve it using a table?
It is easier to solve a quadratic equation by factoring when the equation can be expressed as a product of two binomials that easily yield integer roots. This method is often quicker for simpler quadratics with small coefficients. In contrast, using a table to find solutions can be more cumbersome and time-consuming, particularly for equations where the roots are not integers or when the quadratic is more complex. Thus, factoring is preferred when the equation allows for straightforward factorization.
