do by formula​

Answer 1

Answer:

4x−1)(x+2)=2+7x

Use the distributive property to multiply 4x−1 by x+2 and combine like terms.

4x

2

+7x−2=2+7x

Subtract 7x from both sides.

4x

2

+7x−2−7x=2

Combine 7x and −7x to get 0.

4x

2

−2=2

Add 2 to both sides.

4x

2

=2+2

Add 2 and 2 to get 4.

4x

2

=4

Divide both sides by 4.

x

2

=

4

4

Divide 4 by 4 to get 1.

x

2

=1

Take the square root of both sides of the equation.

x=1

x=−1
