(a ± b)² = a² ± 2ab + b² . . . . . . . (signs match)
The middle term is twice the product of the roots of the other two terms. This tells you the terms of the binomial are the square roots of the end terms.
The sign in the binomial will match the sign of the "2ab" term. The order of terms in the binomial doesn't matter. (a±b)² = (b±a)² when signs match.
Answer:
the answer is 1/2
Step-by-step explanation:
i solved it
2 5/6 = 2.83
1 3/4 = 1.75
2.83*1.75= 4.9525
I think you have to count 85 and go down like 85 86 87so the answer is 15
Step-by-step explanation:
Given bi-quadratic equation is:
Substituting 
given bi-quadratic equation reduces in the form of following quadratic equation:
Let us factorize the above quadratic equation:
Since square root of a negative number cannot be found, so:
