Answer:
Solution given:
Since it is a form of (a+b)²
we have
(a+b)²=a²+2ab+b²
here
a=x
b=b/2a
now
substituting value
x²+2*x*b/2a+(b/2a)²
2(x + 4) = -10 |divide both sides by 2
x + 4 = -5 |subtract 4 from both sides
x = -9
There are multiple… like 14:30 and another would be 35:75
Just multiply each side by the same amount like with 14:30 I multiples 7 by 2 so I multiples 15 by 2 also and for 35:75 I multiplied 7 by 5 and 15 by 5 if that helped at all :)
