Question

divide:2a³+11a²+19a+15 by 2a+5

Answer 1

Answer:

• 26/4 or 6.5

Step-by-step explanation:

• 2a+5
• just equal the divisor by 0
• 2a+5=0
• 2a=0-5
• a=-5/2

now we will pot the value of a

• 2a³+11a²+19a+15
• 2×(-5/2)³+11×(-5/2)²+19×-5/2+15
• 2×-125/8+11×25/4-95/2+15
• -125/4+275/4-92/2+15
• LCM of 4,4,2 will be=4
• (-125+275-184+60)/4
• (275+60-125-184)/4
• (335-309)/4
• 26/4

or in decimal form

• 6.5
