Answer 1

Answer:

Step-by-step explanation:

Suppose (a + b) and (c + d) are two binomials. By using the distributive law of multiplication over addition twice, we may find their product as given below. (a + b) × (c + d) = a × (c + d) + b × (c + d) = (a × c + a × d) + (b × c + b × d) = ac + ad + bc + bd Let, a= 5x, b= 7, c= 3x, d= 4 Now, = 5x × (3x + 4) +7 × (3x + 4) = [(5x × 3x) + (5x × 4)] + [(7 × 3x) + (7 × 4)] = [15x2 + 20x + 21x + 28] = [15x2 + 41x + 28]Read more on Sarthaks.com - https://www.sarthaks.com/749092/find-the-product-5x-7-3x-4
