Question

Please tell me the answer to this question. Give a step by step explanation as well.

Answer 1

Answer:

15d^2 +7d-4

Step-by-step explanation:

(5d+4)(3d-1)

FOIL

first 5d*3d = 15d^2

outer 5d(-1) = -5d

inner 4*3d = 12d

last 4*-1 = -4

Add together

15d^2 -5d+12d -4

15d^2 +7d-4

Answer 2

$\boxed{\large{\bold{\textbf{\textsf{{\color{blue}{Answer}}}}}}:)}$

• $\sf{(5d+4)(3d-1) }$

• $\sf{ 5d(3d-1)+4(3d-1) }$

• $\sf{15d^2-5d+12d-4 }$

• $\sf{15d^2+(-5+12)d-4 }$

• $\sf{ 15d^2+7d-4 }$
