Consider the equation 9x+3=x−1. Squaring the left side and simplifying results in _______. Squaring the right side and simplify

bixtya [17]

Answer:

The first blank is 81 $x^{2}$ +9=x-1

The second blank is 9x+3=x^2-1

Step-by-step explanation:

For the first part, you must set up the equation (9x+3)^2 then you must multiply the exponent to the inside exponents $9^{2} x^{2}$ + $3^{2}$ next, simplify.

81 $x^{2}$ +9=x-1

For part two, set up equation. $x^{2} -1^{2}$ Then simplify 9x+3= $x^{2} -1$
