26. \( \frac{x+3}{x^{2}-25}-\frac{x-1}{x-5}+\frac{3}{x+3} \)

(b) \( 27 x^{2}-3 y^{2} \)

Use the point-slope form to write an equation of the line with the given slope and point. Then write the equation in slope-intercept form. slope 4 , passes through \( (4,6) \)

A. Déterminer la forme canonique de chacun des polynômes suivants : 1. \( P(x)=3 x^{2}-6 x+9 \) 2. \( P(x)=-5 x^{2}+3 x+12 \) 3. \( P(x)=9 x^{2}-7 x \)

Find the slope and the \( y \)-intercept of the line with the given equation. \[ 4 x+3 y=9 \] slope \( y \)-intercept \( (x, y)=(\square) \) Submit Answer

Factorise coumpletely. \( 21 a^{2}+28 a^{b} \)
