Question :–
• Find the roots of quadratic equation x² + x - 30 by middle term splitting.
ANSWER :–
GIVEN :–
• A quadratic equation x² + x - 30 = 0.
TO FIND :–
• Roots by middle term splitting = ?
SOLUTION :–
⇒ x² + x - 30 = 0
• We should write this as –
⇒ x² + 6x - 5x - 30 = 0
⇒ x(x + 6) - 5(x + 6) = 0
⇒ (x - 5)(x + 6) = 0
⇒ x - 5 =0 & x + 6 = 0
⇒ x = 5 & x = -6
⇒ x = 5 , -6
• Hence , The roots are 5 & -6.
