Question

Find the roots of the following quadratic equations by factorization. t² − 7 = 0

Answer 1

Answer:

tsquate=7=t=root7=t=2.645

Answer 2

${t}^{2} - \sqrt{7} {}^{2}$

using

${a}^{2} - {b }^{2} = (a + b)(a - b)$

so it will be

(t-√7)(t+√7)=0

we get two values of t as

$t = + \sqrt{} 7 and - \sqrt{} 7$
