Answer:
This was answered earlier for you by myself the answer is certainly x^2+ 3x-4x + 3 - 3 = x^2 - x if you wanted to solve for x you show x^2 - x = 0 and do the abc formula -b+- sqrt b^2 -4 * a * c / 2 * a = - 1 +- sqrt 1 - 4 * 1 = -1 (sqrt 1-4) / 2)) = -1 sqrt -1 1/2 sq rt is not true for domain ≠ -1 1/2 so on number line we draw a hybrid number line showing -1 1/2 -1 1/2 0 1/2 1 1 1/2 and show circles at - 1 1/2 going left to - infinity and open circle at 1 1/2 going right to positive infinity and show this to be our only true solution for x as x ≥ 1 1/2 with domain = D = ( 1 1/2 ) INFINITY) meaning compared to divisions of inequalities we can show a union usually but with squares in equation there is NO UNION we find positive rule does rule so therefore any suggestion of negatives = x are untrue they only appear on first number line and we need a set of 2 number lines to prove the product rule where minus multiplied by minus = + left side and central negative - multiplied by + is also negative so we keep the middle section true for first number line but not for the square element so therefore we keep open circle for both - 1 1/2 and + 1 1/2 and only show the domain as true for positive therefore x = 1 1/2
Step-by-step explanation:
first bold is the equation asked in question 2nd bold is the answer to finding x and proving why x is positive
