Chapter 6: Q. 298 (page 627)

In the following exercises, solve:

y-3y+2=4y

Short Answer

Expert verified

On solving the equation, we get y=6,-1.

Step by step solution

01

Step 1. Given information.

Consider the given equation,

y-3y+2=4y

Write the quadratic equation in standard form,

y2+2y-3y-6=4yy2-5y-6=0

02

Step 2. Factor the quadratic expression.

On factoring, we get,

y2+y-6y-6=0yy+1-6y+1=0y-6y+1=0

Use the zero product property,

y-6=0y=6

Then,

y+1=0y=-1

03

Step 3. Check the answers.

Substitute y=6in the given equation,

6-36+2=4638=2424=24

This is true.

Substitute y=-1in the given equation,

-1-3-1+2=4-1-41=-4-4=-4

This is also true.

Hence, the answer isy=6,-1.
