Answer 1

Step-by-step explanation:

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Question :-

• split the expression t^2-4t-20

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Solution :-

According to the quadratic formula :-

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

There are two method for solving quadratic equations

1) By Factorisation method :

2) By Sridhar Acharya's method

Formula :-

x = -b ± √b^2-4ac/2a

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Solving :-

Ax^2+bx+C =0

Applying :

A = 1. B = -4. C = -20

x = -b ± √b^2-4ac/2a

Solving :-

X = - (-4) ± √-4^2-4×1×-20/2×1

X = 4 ± √16 +80/2

X = 4 ± √96/2

Answer is :-

X = 4 + √96/2

X = 4 - √96/2
