Hey there!

x^2 + x = 12

SUBTRACT 12 to BOTH SIDES

x^2 + x - 12 = 12 - 12

SIMPLIFY IT!
x^2 + x - 12 = 0

SET the FACTORS to EQUAL to 0

x - 3 = 0 OR x + 4 = 0

SIMPLIFY IT!
x = 3 or x = -4


Therefore, the answer is:

x = 3 or x = -4


Good luck on your assignment & enjoy your day!

Answer:

<u>x = 4 and x = -3</u>

Step-by-step explanation:

⇒ x² + x = 12

⇒ x² + x - 12 = 0

⇒ x² + 3x - 4x - 12 = 0

⇒ x(x + 3) - 4(x + 3) = 0

⇒ (x - 4)(x + 3) = 0

⇒ <u>x = 4 and x = -3</u>

A rectangular plot of land that contains 1500 square meters will be fenced and divided into two equal portions by an additional
WINSTONCH [101]
Let x = the length of the rectangle
Let w= the width

Two sections are required, hence 2w of fence required
2x+3w=500

this can be written as:
3w=1500-2x
w=(1500-2x)/3

Area=x*w
replacing w with our expression:
A=x(1500-2x)/3
A=(500x-2x^2)/3

This is a quadratic equation, if we find the axis of symmetry we will know what value of x gives maximum area:
Axis of symmetry: x=-b/2a
From our equation we get:
a=-2/3; b=1500/3
thus
x=(1500/3)/(-(-2/3))
x=750
thus the maximum area will be given by length of 750
