Q. Determine the x-intercepts of the following equation.(−x+5)(x−3)=y(−15,0)(0,−15)(5,0) and (−3,0)(5,0) and (3,0)(0,5) and (0,3)(0,15)
Set y to 0: To find the x-intercepts of the equation, we need to set y to 0 and solve for x. This will give us the points where the parabola crosses the x-axis.(−x+5)(x−3)=0
Apply zero product property: Now we have a product of two factors equal to zero. According to the zero product property, if the product of two factors is zero, then at least one of the factors must be zero.So we set each factor equal to zero and solve for x:−x+5=0 or x−3=0
Solve −x+5=0: First, we solve the equation −x+5=0 for x.−x+5=0−x=−5x=5
Solve x−3=0: Next, we solve the equation x−3=0 for x.x−3=0x=3
Identify x-intercepts: We have found two x-intercepts: (5,0) and (3,0). These are the points where the parabola crosses the x-axis.
