explanation for extracting the square roots, (can't be done using this method) explain why? x²+5x-14=0
Answer (1)
Answer:The roots are -7 and 2.Step-by-step explanation:Extracting the square roots method can't be used in this equation since the value of b≠0. Instead, we can use the factoring method.x²+5x-14=0(x+7)(x-2)=0To get the value of the roots:x₁= x+7=0x=0-7x₁= -7x₂= x-2=0x=0+2x₂= 2Therefore, the roots of the quadratic equation x²+5x-14=0 are -7 and 2.
