Question

A rectangular rig has area of (2x²+x-28)m².the length of rug is (x-4)m.what is the width ​

Answer 1

Step-by-step explanation:

area = (2x²+x-28)m²

length= (x-4)m

so area= l×b

= (x-4)(2x²+x-28)

= 2x³+x²-28x -8x²-4x + 112

=2x³-7x² -32x + 112

now 1st apply the hit and trial method and then factorise it .
