After solving the equation,we get,(x + 5)(x – 3) = x(x – 3) + 5(x – 3)= x2 – 3x + 5x – 15= x2 + 2x – 15

Q3 of 95 Page 94

(x + 5) (x - 3) = ?

After solving the equation,

we get,

(x + 5)(x – 3) = x(x – 3) + 5(x – 3)

= x² – 3x + 5x – 15

= x² + 2x – 15

The sum of (6a + 4b – c + 3), (2b – 3c + 4), (11b – 7a + 2c - 1) and (2c – 5a - 6) is

(3q + 7p² – 2r³ + 4) – (4p² – 2q + 7r³ – 3) = ?

(2x + 3)(3x - 1) = ?

(x + 4)(x + 4) = ?
