Step-by-step explanation:
Answer:
x<3 and x<5
Step-by-step explanation:
Given the quadratic inequality x² - 8x + 15 <0, to get the solution set for the inequality, the following steps must be followedStep 1: Factorize the quadratic expression
x² - 8x + 15 <0
x² - 3x - 5x + 15 <0
x(x - 3) - 5(x - 3) <0
(x -3)(x -5)< 0
x -3<0 and x -5<0
x< 3 and x< 5
