Pair of equations

How can you solve the system

without graphing? (i. e. , algebraically)

I know the answers approximately, having graphed as a last resort.

I tried substitution, but to no avail.

Guidance?

It's a quadratic equation. The first line gives an expression for b in terms of a; rewrite the second line in those terms and resolve to get your quadratic. Notinasnaid 11:06, 1 May 2006 (UTC)Yes, the canonical method is the Viète's formulas. 1. Let's see:x = a or x = b is equivalent to 0 = (x âˆ’ a)(x âˆ’ b) = x2 âˆ’ (a + b)x + ab = x2 âˆ’ 10x + 10 from which you get , thus and or the same two values swapped. - b_jonas 11:19, 1 May 2006 (UTC)Algebra solves this easily, but we can also approach numerically. Since the product of a and b is positive, either both are positive or both are negative; and since their sum is also positive, we conclude that 0 < a,b < 10. Actually, we can do better, because if one factor is 10 the other is 1, and if one summand is 1 the other is 9. Repeat! If one factor is 9 the other is 10â„9, and if one summand is 10â„9 the other is 80â„9. Top Ad & Spyware Remover. Then we get 9â„8 and 71â„8; then 80â„71 and 630â„71; then 71â„63 and 559â„63. Numerically we now have 1. 127 and 8. 873, which are correct to the number of decimal places given. In fact, the last two steps agree to this precision, so we seem to have converged to an answer. Eliminate virus threats from shared files, e-mail, 'net downloads, and more. The correct answers are approximately 1. 1270166537926 and 8. 8729833462074, so we have done well. As requested, we solved the system without graphing. In this particular case we could get an exact expression with algebra, but in more complicated cases it's good to have more tools. remove sub seven.
