Q. Solve for x. Enter the solutions from least to greatest.x2+3x−28=0 lesser x=□ greater x=□
Find two numbers: Find two numbers that multiply to −28 and add up to 3. The numbers that satisfy these conditions are 7 and −4 because 7×(−4)=−28 and 7+(−4)=3.
Write equation in factored form: Write the equation x2+3x−28=0 in its factored form using the numbers found in the previous step. This gives us (x+7)(x−4)=0.
Solve for x (part 1): Set each factor equal to zero and solve for x. First, set x+7=0 and solve for x. Subtracting 7 from both sides gives us x=−7.
Solve for x (part 2): Now, set x−4=0 and solve for x. Adding 4 to both sides gives us x=4.
Final solution: We have found two solutions for x: −7 and 4. To answer the question prompt, we need to enter the solutions from least to greatest. The lesser value is −7, and the greater value is 4.
