Question

5x(x+3)+1(x+3)-8=(x+1) (x+2)
solve for x

solve=5x(x+3)+1(x+3)-8 =5[x(x+2)+1(x+2)]
= 5x2+15x+x+3-8
= 5(x2+2x+x+2)
= 5x2+16x-5
= 5x2+15x+10
= 5x2-5x2+16x-15x
= 10+5
x=15
Hence answers is 15

Your answer is correct

Answer 2

Answer:

Here is the answer. ...❤❤

5x(x+3)+1(x+3)-8 =5[x(x+2)+1(x+2)]

= 5x2+15x+x+3-8

= 5(x2+2x+x+2)

= 5x2+16x-5

= 5x2+15x+10

= 5x2-5x2+16x-15x

= 10+5

x=15

Hence the answer is 15....
