When the first equation is multiplied by -3, the sum of the two equation
and any of the original equations will have the same solution as the
original equations. Hence 5x = -10 and 11x - 9x = -13 will have a
solution of (-2, -1).
I took a picture of the answer for you.
Answer:
no
Step-by-step explanation:
A portion of the Quadratic Formula proof is shown. Fill in the missing statement. Statements Reasons x squared plus b over a times x plus the quantity b over 2 times a squared equals negative 4 times a times c all over 4 times a squared plus b squared over 4 a squared Find a common denominator on the right side of the equation x squared plus b over a times x plus the quantity b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Add the fractions together on the right side of the equation the quantity x plus b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Rewrite the perfect square trinomial on the left side of the equation as a binomial squared x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a squared Take the square root of both sides of the equation ? Simplify the right side of the equation x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a squared x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over a
