Question:
Quadratic equations Please Help Me!!!!!!
Answer:
The roots are 1 +√7 and 1 -√7.
What is Quadratic equation?
A quadratic equation in the variable x is an equation of the form ax² + bx + c= 0, where a, b, c are real numbers, a≠0
Given equation:
y= x²+2x-6
First,
Half the coefficient of x and add and subtract the square of (b/2)
y= x²+2x-6+(1)²-(1)²
y= x²+2x+(1)² -6 -(1)²
y= (x+1)² -7
Now, equate y=0
(x+1)² -7 =0
(x+1)² = 7
x+1= ±√7
x=1 ±√7
Hence, the roots are 1 +√7 and 1 -√7.
They may hopefully help the student answer the question by making use of the questions and answer examples. You could simply then have a discussion with your classmate and continue the school learning by studying the subject altogether.
