Factor the expression completely.<br> 25x2-65x - 30
Anton [14]

Answer:

\large\boxed{25x^2-65x-30=5(x+3)(5x-2)}

Step-by-step explanation:

25x^2-65x-30=5(5x^2-13x-6)\\\\=5(5x^2-15x+2x-6)=5\bigg(5x(x-3)+2(x-3)\bigg)\\\\=5(x-3)(5x+2)

What is the point slope form of the line with slope -3/7 that passes through the point (5’8)?
maksim [4K]

Step-by-step explanation:

The point-slope form of a line is given by

y - y_1 = m(x - x_1)

where (x_1, y_1) is the point on the line. So we can write the equation as

y - 8 = -\frac{3}{7}(x - 5)
