(x+3)^2 = x^2-3(1-x)

Oxana [17]

(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4

Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)

Please help on dividing fraction you have to do keep change flip

sasho [114]

Remember:
(a/b)÷(c/d)= $\frac{ \frac{a}{b} }{ \frac{c}{d} }=( \frac{a}{b} )( \frac{d}{c} ) = \frac{ad}{bc}$
so
(7/10)÷(1/5)= $\frac{ \frac{7}{10} }{ \frac{1}{5} }=( \frac{7}{10} )( \frac{5}{1} ) = \frac{(7)(5)}{(10)(1)}= \frac{35{10}= \frac{7}{2}$

the answer is 7/2
