Answer:1. x=62. x=9Step-by-step explanation:for 1:remove the 4 by dividing 4 on both sides, making it(x²-12x+36)=0then find the factor by finding the square root of "c"(x−6)²=0then extract the roots on both sidesx-6=0x=0+6x=6for 2:remove the 2 by dividing 2 on both sides, making it (x²-18+81)=0then find the factor by finding the square root of "c"(x−9)²=0then extract the roots on both sidesx-9=0x=0+9x=9
