Answer :
Answer:
23
Step-by-step explanation:
x^2 + 43 = 572
x^2 = 572 - 43
x^2 = 529
( 529 = 23 x 23 = 23^2 )
x^2 = 529
x^2 = 23^2
x = 23
X^2+43=572
X^2=572-43
X^2=529
X=+23
Write the solutions, one with a sign and one with a sign
X=-23
X=23
X^2=572-43
X^2=529
X=+23
Write the solutions, one with a sign and one with a sign
X=-23
X=23
