Question Simplify the expression 49m2+98m+49 Evaluate (−7m−7)2A negative base raised to an even power equals a positive (7m+7)2Use (a+b)2=a2+2ab+b2 to expand the expression (7m)2+2×7m×7+72Solution 49m2+98m+49 Show Solution Factor the expression 49(m+1)2 Evaluate (−7m−7)2Evaluate 49m2+98m+49Solution 49(m+1)2 Show Solution Find the roots m=−1 Evaluate (−7m−7)2To find the roots of the expression,set the expression equal to 0 (−7m−7)2=0The only way a power can be 0 is when the base equals 0 −7m−7=0Move the constant to the right-hand side and change its sign −7m=0+7Removing 0 doesn't change the value,so remove it from the expression −7m=7Change the signs on both sides of the equation 7m=−7Divide both sides 77m=7−7Divide the numbers m=7−7Solution More Steps Evaluate 7−7Reduce the numbers 1−1Calculate −1 m=−1 Show Solution
