Answer 1

Answer:

Take this answer!!!!!!!!!!

Step-by-step explanation:

(5y-3)(2y+5)

=5y*2y+5y*5-3*2y-3*5

=10$y^{2}$+25y-6y-15

=10$y^{2}$+19y-15.

ANSWER IS: =10$y^{2}$+19y-15.

Answer 2

Multiply -

• (5y - 3)(2y + 5)

Solution -

$\mapsto$ $\bold{5y(2y + 5) -3(2y + 5)}$

$\mapsto$ $\bold{(10 {y}^{2} + 25y) -(6y + 15)}$

$\mapsto$ $\bold{10 {y}^{2} + 25y -6y - 15}$

$\mapsto$ $\bold{10 {y}^{2} + 19y - 15}$

Answer =}

$\bold{19y + 10 {y}^{2} - 15}$
