and
x+4=0
EXPLANATION
Given that:
Then to find roots of
is the same as finding the roots of
By the zero product property, we must have either,
Hence the equations that must be solved to find the roots are:
2x-3=0
and
x+4=0

Answer:
<h2>x = 28</h2>Step-by-step explanation:
ΔARP and ΔCRD are similar. Therefore the sides are in proportion:
We have:
AR = 10 + x
CR = x
PR = 15 + 42 = 57
DR = 42
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 42x from both sides</em>
<em>divide both sides by 15</em>
