About 5 books have been signed out, so they still have 4.
7 is the most common in this expression.
therefore to factorise, you will choose the most common factor.
the answer will be -7(r+5x)
<span>√x^2+2x-10=√x+20
raising both members to the square
</span> x^2+2x-10=x+20
rewriting
x^2+x-30=0
factoring
(x+6)(x-5)=0
therefore the solutions are
<span> x = –6, x = 5
</span>the answer is
<span>B. x = –6, x = 5</span>
