Question

Multiply (x+2) by (3 x+1)
$(x + 2)(3x + 1)$
​

Answer 1

Explanation:

Let the present ages of M and N be 5x years and 3x years respectively.

Given (5x−4):(3x+4)=1:1 ⇒ 5x−4=3x+4

⇒2x=8⇒x=4

∴ Present ages of M and N respectively are (5×4) years and (3×4) years i.e., 20 years and 12 years

Answer 2

Answer:

(x + 2) (3x + 1)

= x(3x + 1) + 2(3x + 1)

= 3x^2 + 1x + 6x + 2

=3x^2 + 7x + 2
