Chapter 9: Q. 134 (page 898)

In the following exercises, solve by using the Quadratic Formula.
(x+1)(x-3)=2

Short Answer

Expert verified

The solutions of the given equation are x=1卤6.

Step by step solution

01

Step 1. Write the quadratic equation in standard form.

The given equation is:

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

The given equation can be written as:

x2-3x+x-3=2x2-2x-3-2=0x2-2x-5=0

02

Step 2. Substitute the values in Quadratic Formula.

Quadratic Formula for the equation ax2+bx+c=0is:

x=-b卤b2-4ac2a

In the given equation, a=1,b=-2,c=-5. Substitute these values in Quadratic Formula.

x=-(-2)卤(-2)2-4(1)(-5)2(1)

03

Step 3. Simplify the value.

On simplification, we get

x=2卤4+202x=2卤242x=22卤262x=1卤6

04

Step 4. Conclusion.

The solutions of the given equation are x=1卤6.
