Question Simplify the expression 289+136x+16x2 Evaluate (−17−4x)2A negative base raised to an even power equals a positive (17+4x)2Use (a+b)2=a2+2ab+b2 to expand the expression 172+2×17×4x+(4x)2Solution 289+136x+16x2 Show Solution Find the roots x=−417Alternative Form x=−4.25 Evaluate (−17−4x)2To find the roots of the expression,set the expression equal to 0 (−17−4x)2=0The only way a power can be 0 is when the base equals 0 −17−4x=0Move the constant to the right-hand side and change its sign −4x=0+17Removing 0 doesn't change the value,so remove it from the expression −4x=17Change the signs on both sides of the equation 4x=−17Divide both sides 44x=4−17Divide the numbers x=4−17Solution x=−417Alternative Form x=−4.25 Show Solution
