Question

FIND THE PRODUCT using identities (y + 3z) (y + 5z) brainly

Answer 1

Answer:

y^2+15z^2+8yz

Step-by-step explanation:

y^2+5yz+3yz+15z^2

=y^2+15z^2+8yz

this is basic algebraic multiplication and addition

Answer 2

Answer:

Sure!

This is in the form

(x+a)(x+b)

So the identity for this is

$x^{2}$+(a+b)x +ab

Which will be

$y^{2}$+ (3z+5z)y + (3z*5z)

$y^{2}$ + 8zy+ 15$z^{2}$

Solved

Hope this helps u :)
