Q. Solve the equation −14x+15=−x2 to the nearest tenth.Answer: x=
Rewrite equation in standard form: Write the given equation in standard quadratic form.To solve the quadratic equation, we need to rearrange it into the standard form ax2+bx+c=0.The given equation is −14x+15=−x2.We can rewrite it as x2−14x+15=0 by adding x2 to both sides and rearranging the terms.
Factor the quadratic equation: Factor the quadratic equation.We need to factor the quadratic equation x2−14x+15=0.The factors of 15 that add up to −14 are −1 and −15.So, we can write the equation as (x−1)(x−15)=0.
Solve using zero product property: Solve for x using the zero product property.If (x−1)(x−15)=0, then either x−1=0 or x−15=0.Solving for x gives us x=1 or x=15.
Round solutions: Round the solutions to the nearest tenth. The solutions x=1 and x=15 are already to the nearest tenth, so no further rounding is necessary.
