Q. x−1=(2−x)2What are the solutions to the given equation?Choose 1 answer:(A) x=0(B) x=25−5 andx=25+5(C) x=2−1−21 andx=2−1+21(D) The equation has no real solutions.
Expand equation: First, we need to expand the right side of the equation (2−x)2.(2−x)2=(2−x)(2−x)=4−4x+x2
Rewrite equation: Now, we rewrite the original equation with the expanded form: x−1=4−4x+x2
Arrange equation: Next, we bring all terms to one side to set the equation to zero and arrange it in descending order of powers of x:x2−4x+x−4+1=0x2−3x−3=0
Quadratic formula: We now have a quadratic equation. To solve for x, we can use the quadratic formulax=2a−b±b2−4ac, where a=1, b=−3, and c=−3.
Solve using formula: Plugging the values into the quadratic formula:x = [−(−3)±(−3)2−4(1)(−3)]/(2(1))x = [3±9+12]/2x = [3±21]/2
Simplify solution: Simplifying the square root and the expression:x=23±21So we have two solutions:x=23+21x=23−21
Compare solutions: We compare our solutions with the given options:(A) x=0 (Incorrect)(B) x=25−5 and x=25+5 (Incorrect)(C) x=2−1−21 and x=2−1+21 (Incorrect, sign error in the constant term)(D) The equation has no real solutions. (Incorrect, we found real solutions)
