Step-by-step explanation:

a + 3) (a + 5)

This is in the form. (x + a)(x + b) = x² + (a + b)x + ab

Here x = a, a = 3, b = 5

(a + 3)(a+ 5) = a² +(a + 5)a + 3.5

= a² + 8a + 15

(ii) (3t + 1)(3t + 4)

This is in the form (x + a)(x + b) = x² +(a + b)x + ab

Here x =3t,a = 1, b = 4

(3t – 1)(3t + 4) = (3t)²+(1+ 4)3t + 1.4

= 9t² +5(3t) + 4 = 9t² +15t + 4
